guess what the response of authoritarian followers here in germany would be:
"he is obviously a anti-Semite/jew hater".
If you criticise Israeli actions and war crimes you are automatically put into this box.
so maybe a text on the backside of the Shirt would be good something like this:
"Race, skin color or ancestry is not the problem. The problem is that we are Ruled by Psychopaths !"
or
"Race, skin color or ancestry is indifferent. The problem is Psychopaths in positions of Power !"
Edit:
or more to the point that nobody can blame you are a Nazi:
"I'm not a anti-Semite, Nazi or Jew hater! Race, skin color or ancestry is indifferent. The problem is Psychopaths in positions of Power !"
