Is this a known anti semitic site?

[question everything]

6. I thought that there was a ban on posting from clearly right wing source

but cannot find such a ban.

Still, while looking at some of the rule, was glad to find this:

No bigoted hate speech.

Do not post bigotry based on someone's race or ethnic origin, gender, sexual orientation, gender identity, religion or lack thereof, disability, or other comparable personal characteristic. To be clear: This includes any post which states opposition to full equal rights for gays and lesbians; it also includes any post asserting disloyalty by Jewish Americans, claiming nefarious influence by Jews/Zionists/Israel, advocating the destruction of the state of Israel, or arguing that Holocaust deniers are just misunderstood. In determining what constitutes bigotry, please be aware that we cannot know what is in anyone's heart, and we will give members the benefit of the doubt, when — and only when — such doubt exists.
