How was this particular fellow involved in that state execution? 
sins of the father.What a silly concept
instead of going around calling the rest of the world mentally ill for disliking them
You assume that the rest of the world is disliking them. Who is "them"? Who are "the" jews?
enemy stereotypes are about throwing all people of an ethnic/religious group in one pot.
This is never a good idea, not for muslims/christians/jews/hindus etc.
