I think the main issue that people have with some Christians having a say in their own government is the fact that most of the time some Christians want to force legislation on people that would require them to adhere to "Christian" standards. It's not the fact that you are Christian that gets you demonized, it's the fact that you want to force others to live by your values and your standards. That has nothing to do with your faith and everything to do with telling people how to live.
So, as I have said many times...some Christians make themselves a target for attacks because of the force they want to put on other people. If they lived by a live and let live attitude, I doubt many people would have issue with it.
Live and let live was the attitude right up until our very rights to practice freely began to be violated.
The laws you keep blaming on Christians were there because most everyone was Christian. Then, for a while, there were growing non-Christian minorities who nevertheless found Christian values more than adequate.
It was only with the advent of the socialist agenda and the "sexual revolution" that small minorities of not just non-Christian, but actively anti-Christian groups began to systematically attack everything Christian, including trying to destroy the Christian artifacts that are the heritage of our over 200 year old nation, attempting to remove by force the evidence that this is indeed a Christian nation.
Taliban like, when they blew up those ancient statues of Buddhists, anti-Christians voraciously attack Christianity wherever they find it, all the while smiling and claiming to be "moderate" even when they attack things that 60, 70, even 80% of people disagree with.
It is NOT, it is NOT, it is NOT Christians who are pushing their agenda unethically in this country. This country is not like Europe precisely because of this sort of harassment there, which drove our ancestors HERE.
There's no place left for us to run. We need to take our stand here, or understand very clearly that, as one of the other posters here has pointed out, that this could easily be the end of time, and it is our generation that is dropping the ball.
Rev 3:15-16
15 I know thy works, that thou art neither cold nor hot: I would thou wert cold or hot.
16 So then because thou art lukewarm , and neither cold nor hot, I will spue thee out of my mouth.
KJV
I could be mistaken, but I think we can have something to say about whether we are that generation. If we are to be harassed, let's at least make a showing for ourselves for the sake of the truth.
