the word antisemitic has not been trivialised by any other then those who wish to avoid the label. However maybe you can show you aren’t antisemitic by avoiding the language that marks you out as one and by calling out some of the most vile anti semitic, Jewish hating posts and correcting those who try to dismiss antisemitism by redefining it - stating that Palestinians too are semites. The latter may be true but the work anti semiotic was coined specifically to refer to Jew hating and has never been used in any other sense .
