The person you are responding to characterized antisemitism as "supposedly committing racist actions" which is an ignorant and hateful thing. You are arguing whether or not the existence of a word "still is justified". Words don't need to be justified or not; they go in or out of favor based on utility.

This holocaust denialism. One of the major and specific problems with the nazis was their attitude regarding jews. They didn't have a problem with "minorities". They used long standing conspiratorial intolerance to consolidate power into the hands of their minority.
One of the reasons israel thinks it can keep riding the "everything is antisemetic" horse is because of how comfortable people clearly are with actual anti semitism.
No. Collective punishment is a crime.
