Honestly it's generally just easier to say you're an agnostic. It's basically the same thing as weak atheism "It's impossible to prove (but I don't think it's particularly likely)" but people don't assume you're some kind of obnoxious redditor at best or psychopath at worst.
It's still bullshit, atheism is perfectly good as a lack of religious belief and it shouldn't be stigmatized, but it is worth nothing that while the term should be reclaimed, there's been literal thousands of years of atheism being demonized around the world.
Some people hear "atheist" and their brain just corrects to "adolator" or "enemy of God". At the very least, it feels like a personal attack, like, "who are you to say that my God isn't real?"
So, I mean, feel free to use the term "atheist", it's a good term, it's just that people at best can take it as an attack and at worst will assume that you're devilspawn, depending on the person.
