Meaning that God's own people are spared by whatever the suffering of the consequences of these bad deeds are (like a mass crisis, EMP burst, nuclear war, etc.)
I guess you're referring to what's popularly referred to as the pre-trib rapture, where all of God's people are sucked up into Heaven before anything bad happens to them. This is a popular belief but it's not based either on scriptural evidence or just practical reality.
There's two major divisions of disaster in the Revelation; 7 trumpets of Great Tribulation and 7 bowls of wrath. Tribulation is something all humans experience, including God's people. Tribulation is God's way of getting us back to reality. For example, you're happily walking down the street after you just bought some frivolous thing that you've been wanting for a long time, then suddenly there's an earthquake and you're able to save a kid from some falling rubble. You saved the kids life, but the rubble hit you in the shoulder and now your arm will never work the way same again. You feel some regret about this but the fact that you saved a life puts the situation into a manageable and meaningful context. Your suffering is bearable because it has purpose.
Those Christians who believe so ardently that they will escape all suffering do so because they see no purpose in suffering; they see only inconvenience to themselves. While all humans experience tribulation of some sort (some of us learn from it more than others) Jesus (and the Revelation) describes a time of Great Tribulation, such as the world has never seen before. Far from being some horrible scenario begging escape, this will be the time for Christians to shine. The situation will be horrible precisely because the world as a whole will turn away from goodness; what more practical role could we Christians play than to be a light shining in such darkness even if, and perhaps especially because doing so will cost us our lives? As the saying goes, if you don't have anything worth dying for, then you do not have anything worth living for.
It's also unfair because I'm 28 and want to live my life. But no, if the end times happen that means I cannot do things like get a girlfriend/married or have a family after that, and other things.
When I was 10 I threw a pretty nasty tantrum over not getting a toy I wanted. It just did not occur to me that there was more to life in that particular moment. I suppose from God's perspective we're all continuously going through such phases. 20 years from now I'll remissness back to my life at this time and wonder how I could have been so blind yet again.
Another thing is this. If God considers something like abortion to be a severe abomination, why did God allow abortion activists to mock and even harass anti-abortion people ad-infinitum without consequence until the end?
I think what God would most likely be upset with is the throw-away culture which causes people to believe that sex is a shallow, feel-good-in-the-moment process which requires no responsibility, thought, or care as to the consequence of such interactions, whether emotionally, spiritually, or physically.
That stuff about people getting angry over such things probably comes in a distant second, though to be sure bitterness and hatred are genuine problems, too.
And why should they just be merciful and not fight back and have dignity?
Your idea of dignity is people fighting outside an abortion clinic?
Why must it be held until the "end"?
Every motivation will be held accountable; some sooner than others. I guess you'd prefer God strike people dead on the spot at the moment of sin? If that were the case, you'd not be here to share your discontent.
An analogy may be like you really want to go to a concert or special event that's being held to you, but only being finally "allowed" to see it when the concert or event has already ended anyway?
No. You're participating in the concert right now. A more accurate analogy, regarding your comments, is that you're at the concert, but you've got earphones on playing your own music while complaining to others around you that the band isn't better than you had expected.
