Most of the 8chan demographic comes from two waves:

-Gamergaters who left 4chan after moot banned it on his site

-/pol/ users who left 4chan after moot messed around with it and encouraged /mlp/ to post on it

So yeah, 8chan users are by and large the kind of people who always go on about evil essjaydoubleus destroying Western civilization by posting mean things on Twitter.

You could make the argument that /pol/ doesn't generalize well to 4chan but that's again not really true; the /pol/ ooze is more contained but it's there, seeping through the cracks whenever something related to social justice blows up.
