I try to be tolerant of religious people, but I do think the world would be a better place if Humanism were mainstream. Atheism gets a bad reputation because of its association with Communism.
Atheism gets a bad reputation because a lot of atheists are arseholes.
And I say that as an atheist. Luckily I got my arsehole phase out in high school.
The way I put it is this: anyone who is a convert to something, ANYTHING, can't freaking wait to tell you about it. And often denigrate anyone or anything that is not a convert.
Look at crossfit junkies. Look at vegetarians/vegans. Look at the newly sober. Look at people who found religion late in life. They almost always want to make sure you know about it, and look down on you if you haven't yet "seen the light."
Well, this is a very religious country. Most atheists were not raised atheist. They became disillusioned with religion/theism over time and for various reasons, and now they feel like the wool has been pulled from before their eyes and they finally see the truth. And dammit, they're going to tell EVERYONE about it.
That was me 25 years ago, but luckily it was back in the BBS days, long before social media. I grew out of it.
Now, 95% of people who know me casually would have no clue I'm an atheist. It quite literally doesn't come up.
Mostly because I don't bring it up.
