I don't believe you. I see anti-Israel comments frequently.

No, it's not a stupid take at all. It's the take of a normal, rational person. If we allow every second comment to be "I hate jews", all that will happen is that nobody will visit the website anymore. There's been ample evidence of that. Many new communities started that allow it, and that's what happens 100% of the time. Because a lot of the people who hate jews and blacks are mentally unstable people who aren't even able to interact with others in a normal way.
