There's nothing wrong with saying that unless they think Jewish is a pejorative.
I wouldn't try it again, not just in Era but in other place too.
I posted my art in monster hunter world reddit, and one poster asked why isn't her nose big like the original art?
I replied that it looks too jewish, so I don't do that(it's anime kind fanart, they always have small noses)
I got a straight 14 days ban, and I didn't even mention if it is ugly or etc.
With plenty of comments saying don't be anti-semitic, and another a straight "fuck you OP, take your anime shit away"(this comment is considered woke, not banned)
Then moderators deleted my comment, and because im banned and can't reply, people called me a coward for deleting my comment.... all these happened while i was asleep.
Moderators didn't reply to my appeal. These days, anything can be made into offence.
