Although I'd very quickly stick OP in an oven due to what his people collectively have done to mine going on near a century now, I reckon I have some valid input as to why he may feel that way.
Culture, who here has ever really wanted to be Jewish? Seriously, who has ever looked at Jewish culture & fancied imitating it?
I'd take the rich tapestry of European & American culture any day.
Next is history, they never shut the fuck up about their history (never question why they've been expelled from so many places either, tell themselves the ebil Goyim do it because they're jealous of status as God's favorite children).
There are actually other races that have suffered equal & there are races that have suffered more, but the Jews wail& cry like babies whereas most other races don't (after all who likes a cry baby) next point on History, in terms of art, music & literature they're shit, even jewtown Hollywood, most execs are Jews, but most the talent is Goyim.

Then you've the whole, being a a good Jew is like being the child of James bond super villain, if your not a twisted evil fuck bent on screwing over your fellow human beings then it's gonna be a lonely ass life for you
