i know about anti-Semitic connotations that surround green skin, but is it still considered anti-Semitic even if the character isn't Jewish or connected Jewish culture in any way? they character in question is Catholic, of mixed Latino/Italian heritage, and is essentially a bard, and their skin is green for plot reasons. I don't want to hurt anyone or make anyone uncomfortable but i wasn't sure and wanted to double check before i went any further with developing the plot.
Are green-skinned gentiles antisemitic?
Short answer: no, you’re totally fine.
Longer answer: there are only a few situations where a character outside the specific group being marginalized by a trope can perpetuate the trope. A desexualized, older white woman whose only purpose in the story is to nurture the main character cannot be a Mammy, for example, because the Mammy trope comes from anti-Blackness and the commodification of Black people’s labor specifically. On the other hand, if you’d said you’d written a Christian character who was untrustworthy, greedy, and clannish but happened to have a hooked nose and darker features I’d side-eye this pretty hard.
However, your character doesn’t have any of these specifically antisemitic tropes from what you’ve mentioned, and for another thing, the reptile invader lie is a lot more obscure than just less-wild accusations of sneakiness and greed; many people haven’t even heard of it. Plus, there’s enough distance between green skin and reptilian invaders that especially since your character isn’t Jewish I don’t think anyone will make that connection.
In other words, green gentiles are fine and have nothing to do with us, and I’d even be fine with green Jews as long as there were green gentiles in the same story (or non-green Jews) and there weren’t any additional references to lizard invaders.
For another green character from a book I like see: Regan, the asexual lizard man with anxiety from RoAnna Sylver’sChameleon Moon.
