Never ever ever trust anyone who defends 4chan in any capacity [CW: Discussion of CSAM]
Knew a guy for a while, one of those types who loves to say "most of 4chan isn't bad, it's only /b/ and /pol/, here look at this funny meme they made" I rolled my eyes whenever he said something like this but figured he was just in denial.
Then one day I mentioned to him that I cut contact with someone for defending drawn CSAM, explaining that I did it because it's used to groom minors and accustom them to being sexualized, and his response was "I don't care, it's the parents' responsibility to protect the kids, there should be no legal or moral barrier to what people draw"
Anyone who browses or defends 4chan is a fascist, a pedophile, or most likely both. Every interaction I've had with them only gave me further proof.
Careful, there's a sizable pocket of leftists online who'll accuse you of being a tyrannical purist for even daring to imply that drawn CSAM is fucked up.
I'm a leftist, I have to draw sexual content to pay the bills. I've never accepted a commission for something like that. I would rather go hungry than draw something like that. No idea how a "leftist" would ever defend such a thing.
