No, I'm comparing 4chan to Kiwi Farms. Neither of them have positive reputations. But between the two of them, Kiwi Farms is clearly worse, if only because it's more fringe and has no "base" of support. There is a large cohort of people who are not very familiar with 4chan but will support it philosophically based on right-leaning tribalism and its reputation as a bastion of free speech. Nobody knows Kiwi Farms and anyone who looks them up will find little redeemable about them.

All I'm saying is that if, for example, 4chan has 50% probability of mustering support from the political right, then Kiwi Farms has 25%. And together they have less chance than 4chan would have by itself.

Kiwifarms definitely had a base of support. Go look up one of the threads about Kiwifarms being taken down. The same free speech absolutists who supported 4chan supported it as well.
