Yes, that is what they call "MuhJew" posting basically. Certain anons here do not want to see Mossad or Isreal criticized in any way and will attempt to shut down those who do.
I get that, but most anons from here who refer to 'kikes' are not saying it's the entire race. It's been a well-known unwritten thing around here for a long time. If you check some of the posts who react dramatically to "muhjew" posts, some are just as harmless as even saying the word "Israel" in passing.
Besides, anons shouldn't be taking things personally here anyways. This is an anonymous space where free speech is permitted. Only outsiders cannot grasp this concept.
