4chan isn't a far right website. Nice try bringing up 8chan and then switching it out for 4chan to try to conflate the two. 4chan has an abundance of far right users in certain boards because it allows anonymous posting where most websites do not. This doesn't make it a "far right website". A far right website is a website created specifically for them.

Wikipedia has a "no original research" rule that ensures Kiwifarms, Chris Chan, and Keffals will never get an honest article because only the opinions of journalists matter. Journalists who have to please investors with PC language and fit into their subculture, reporting on things even if it means lying for attention or appealing to certain people.

Keffals started the majority of it.

The best way to prove it would be to read a bunch of threads, Animal Control is a good place to start, and see what the motives for writing them often are. Behind all of the adult language and pejoratives there is an underlying purpose to it all.

While you're there, take note that Kiwifarms explicitly bans harassment of forum topic subjects, the "far-right" image is because of journalists misconstruing their law-of-the-land rules. If it is legal in the US then you can say it there but everything you say will be criticized.

There are also plenty of leftist or centrist users, which you don't hear about because the site promotes good opsec.

The best way to know about something is to dig into it yourself. Citing the summary paragraph on Wikipedia is not research. You will learn nothing by doing that.

Hilariously, you would learn more by just reading Kiwifarms threads because they require members to back up all information, when possible, using tools hosted by third parties which they cannot tamper with. If Kiwifarms collected the info on sircmpwn then that almost certainly makes it genuine on that basis alone. The political compass of the members who posted it is completely irrelevant.
