I'm going to try and keep this short and simple.

I shaved my head a couple months ago and a lot of my friends kept on telling me that i look like the boy in striped pyjamas and i'm jewish to try and annoy me.

This happened when my and some of my friends were in a group chat and one of my friends added a person that me and the person that got added didn't know each other so my friends tried to describe me to her. They kept on bringing up that i was jewish and looked like the boy in striped pyjamas so i sent a picture of a jewish person in a concentration camp(this was what they were describing me as) and asked if i looked like them. This apparently was too far and i'm a dickhead for sending a picture of that and that is too far and inappropriate and i shouldn't be making fun of that kind of stuff (i wasn't making fun of them). I didn't know what i did wrong so i just didn't say anything after that so things didn't get worse between us.

Was i an asshole for sending a picture of a jew in a concentration camp or were my friends just a bunch of butthurt snowflakes?
