Worth remembering that many people died in the holocaust, including Jewish people, disabled people, East Europeans, labour organisers and others.
If it was in good faith, a memorial to people who died in another genocide would be a place to remember all the victims of all the attempts to wipe people off the face of the earth. However, this has become so polarised into 'sides' that can't have a proper conversation, that it looks toxic and yes, antisemitic.
Nazis, Germans, Christians.
IDF, Israelis, Jews.
Not the same as each other.
