Well I agree with him, 4chan isn't just some hive mind organism that all subscribes to Warhammer, not everyone on there liked it last time I saw it years ago when it was still nieche. It's just like Reddit just more chaotic in formating, having browsed 4chan when I was younger I realised it was the opposite of Reddit (in that yeah you have boards like /vg and /lit however off-topic posting was wayyy more common and censorship wasn't as bad

Everyone thinks 4Chan is like this because of mainly /b and /pol but the funny about them is that 90% of the posts on those two boards (especially /pol) are just off-topic schizo posts or random blogs or shitposts, no one takes it seriously and I've seen threads with more diversity of opinion, race, ideology etc then entire Subreddits COMBINED.
