some interesting points which may relate to todays social and political divisions and conflicts.
There are evil people who get into communist stuff while other worldly people can get into religious stuff . . . wherever there is possible power to be had, and opportunity to get what evil people want.
There is secular sex trafficking, while also there have been pedophile predators in clerical costumes.
Yes, communists have killed a lot of people. And how many people have been killed by Protestants and Catholics . . . in earlier history?
I don't intend to evaluate religious groups today by what others have done in the past. Evil people did the killing; not all Protestants and Catholics today are evil.
Worldly people use whatever works for them. By the way . . . I now note how ones are today so busy with pointing at how many people have been murdered by "communists". Well . . . a moment ago, a number of these people were making a major thing about how many unborn people have been killed in the United States!! But now all of a sudden, it's such a big thing how Communists and Muslims have been doing so much killing. And just forget what "Christian" religious people have done.
But what we have now is independence and freedom with individual rights, in the United States. Indians and Mexicans have been slaughtered; so now let us have peace, please be nice to us, now that we have what we want, please. But since we have individual power, now individuals can kill their own unborn with whom they could learn how to love. And we can just keep attention to the Muslims and Communists and to Israeli action in Gaza.
So, even if certain Christian groups and places are not known to be acting violently, how come they and their buildings can be attacked? Possibly it can be because an organized group can be a target, since it can be controlled more or less from the top, thus having all the people below in control. So-o-o-o, then - - a Catholic hierarchy or Protestant organization or a local church can be a target . . . by getting into the leadership so then the whole group might be controlled. This seems to have happened in, for only one example, the American Episcopal church: I have been told the ones at the top are clearly not about the Bible and its moral standards.
And the Methodists have split, I have been told. Well, whoever stays with the "liberal" side of the split might tend to go the way of the leadership so they can be controlled. Meanwhile . . .

. . . now you will have the Biblical Methodists with members who might stay with the conservative part of the split, even if they find they do not agree with what the leaders consider to be Biblical > they won't leave, possibly, because their version of Methodism is all they have left after the split, and they are loyal to the **name** "Methodist". And, like this, there are Episcopals who won't switch to Catholic or Baptist or Congregational (conservative) because they are loyal to the name "Episcopal" and hope to rescue the Episcopal church or at least use the setting to reach others for Christ.
In any case, then, what you could be seeing is how ones seeking power can try to take over a whole group. That can be more efficient than reaching people one at a time > instead, control a group of thousands, even millions, in maybe a few years of effort . . . or spend years reaching to some one person and then go after another one

If you don't care about the people, working on some one person requires "too much" effort.
But Jesus reached people personally. Yes, He handled group activities; however, perhaps our most attention-getting stories are about individuals He helped and how He related personally with Peter and Thomas and Mary and Martha and others. Our Father is personal with each of us, and Jesus calls us individually to come to ***Him*** (Matthew 11:28-30, 1 Corinthians 6:17), but then to share and care as His family (John 13:34, John 17:20-23).
So . . . can we say that a lot of large-scale church organization is about personal relating as God's family????
I would say, basically not. But it is a target, so ones can adopt all the members and use them **without putting much personal attention into each member**. And it can be a target if it is interfering with people getting what they want. And I suppose a number of church people can try to use the numbers of their groups for political and land control purposes. Plus, by trying to control the non-religious in large numbers, this can make the organization a target.
They "might" not be attacking certain religious buildings and groups because they are against the preaching of the cross, then.
And there might be money in the mix.
And ones claiming Islam can want the land. And they seem to have ways of killing other Muslims and anyone else who is not into Islam: and, specifically, Shiites and Sunnis can be killing each other. And the Taliban, once, raided a dancing girl party in Afghanistan, and they killed all the men who were there, since those guys were plainly acting against Taliban rules. And, by the way, in the early Christian scriptures, ones with Moses were told to kill anyone who went against the LORD; there could be times when the obedient ones were told to put to the sword all the others who were not obeying God. Taliban rules of execution can be similar to the rules of the Law of Moses; and the Shia Iranian regime is possibly doing the killing off of ones who the rulers feel are against their basic Shari'ah Law things . . . which is similar to how with Moses the Jews would execute ones who openly went against God.
So the religious ones, then, have taken turns with secular people, in killing for some "reason". Moses did so, by commandment of God. And so, ones later would suppose if they were the right ones, then God would expect them, too, to kill ones found to be against God.
