Unlike 4chan, 8chan isn't a centralized website managed by a single moderation team. Much like on reddit, anyone can create a board on 8chan and there are thousands of them.
Because of that, I don't think it makes sense to treat 8chan as a single community.
But the nature of 8chan's user base isn't being dictated by its design. It's still an overwhelmingly right-wing site that gained its prominence from the Gamergate controversy. As a frequent user of reddit I would openly declare that overall it's an observably left-wing site. People across the political spectrum certainly use it, but it's still a left-wing site. Neither site was designed to cater to a certain types of users. But it seems dishonest to say certain ideologies, sentiments, patterns of speech, etc. don't take prominence on either platform simply because that prominence isn't an intrinsic aspect of the software that these communities use.

It's somewhat true, but still, reddit hosts right-wing communities like /r/the_donald, while 8chan hosts, for example, /leftypol/.
Both sites consist of multiple, separate communities.
To be fair, /leftypol/ has many users who'd get banned from more civil leftist communities before they can finish saying "liberals get the bullet too".
