Last time I shared this opinion on another thread, I got completely downvoted without a single argument besides that I probably don't know any jews and that I am a racist.

Stop prematurely whining about downvotes.

Also, just because you can predict a criticism does not make it less valid.

No, I am not racist. I live in Lithuania

How is this even an argument? Being Lithuanian and being racist aren't mutually exclusive, you can be both, there is no country you can be from that automatically absolves you of racism.

Your base argument is fundamentally wrong too though, people don't dress up as Caesar or the vikings because people think they are metaphorical monsters, people dress up as them because they are low effort and easy to recognize.
