Besides, this policy systemically discriminates against minorities and minority opinions.
Jews are a minority and there are a large number of accounts here that are regularly posting extreme anti-Israel content, that is often exaggerated, misleading, or downright fabricated (such as this post).
If Jewish accounts would try to counter and give their side of the story every time that happens, their accounts would overwhelmingly be about one topic.
This combined with the ability of a majority to downvote a comment to invisibility ensures you get an echo chamber in here that is irrationally bigoted and misinformed.
