Anti-semitism is definitely a set of beliefs.
It is also a pathology.
I suppose we can all be Zionists, now, too, if we want.
The whole scene in human politics is immature and I'm sick of it.
Figure out what works, do that, and shut down the whole system. Leave people alone when they are doing no harm, and I include homosexuality, atheism, drug use, etc. in that.
