I mean, I'll be rather consistent here.
As a Christian who doesn't like being painted with a broad brush, I'd like to think that I at least have returned the same courtesy I would expect from others. I've probably slipped up a few times, I'm not gonna pretend I live up to my own standards.
I'd be quick to denounce the Westboro Baptist Church for their horseshit (I have), quick to criticize Christians who don't think teenagers should be taught about safe sex (I have), willing to welcome a Muslim into my home and smoke a bowl with them if they seem chill (I have).
I do my best to judge people on their own merits and character, be they my best friend's Muslim friend from high school, a Muslim woman who helped me check my textbook out at my college, left-wingers in my family, left-wingers in my religious group, people I engage in discussions with who tell me they're atheists. I don't just assume the muslims are terrorists/horrible bigots, don't just assume the lefties are psychotic, don't just assume someone I meet whose an atheist is an annoying fedora tipper whose gonna try their damnedest to convert me.
However it gets really sketchy for me when we're talking about Mass Migration from nations that have some rather serious widespread cultural problems. I'd say the same thing at the prospect of mass migration of Christians from the CAR, or less developed Christian countries in other parts of the world where gay people are executed. And if we brought Christians from such groups or countries into mine on mass and it lead to problems and people refused to talk about the culture clash for fear of being labeled racist or some other "ist", I'd take issue with that. I'm not saying don't let anyone in from those countries, I didn't support Trump's travel ban, but I am saying there needs to be actual serious screening and not importing massive cultural change into your country with no eye for the potential consequences.
And to keep this measure for measure, I know plenty of people who constantly shit on Christianity, I'm actually close friends with a few of them. I'm not gonna lie and say that doesn't emotionally provoke me or offend me, in fact that's perhaps the easiest way to emotionally offend me. I'm not going to pretend that makes them people of horrible moral character though, or put them on par with racists, otherwise I wouldn't be close friends with so many of them. Yes it can offend me, sometimes seriously, but as a wise man once said "in order to talk about anything important you have to risk being offensive."
They don't agree with my views as a Christian, and they don't owe those views any more respect or reverence than I owe their views as atheists, or that I owe Putinbot's views as a left-winger, or that he owes my views as a right-winger.
And yes, many of them unfairly paint with too broad a brush when it comes to Christians, and that is a fault, but virtually none of us here aren't guilty of painting with too broad a brush along ideological classifications. Most of the right-wingers here have done that with left-wingers, and most of the left-wingers here have done it with right-wingers.
It's a flaw, but not one I'd put on par with judging people on the basis of skin color, just getting swept up in emotion and making an unfair low resolution judgment of people on the basis of something that actually matters.
Now if a fedora tipping atheist starts talking about sending all religious people to reeducation camps or some shit or having the state teach atheism as the right perspective, then I'd start taking issue with that. But no generally fedora tipping atheists with an utter contempt for Christianity are not remotely the same as racists.
