No, the regulars are not openly anti-semitic like neonazis or other cranks would be and some (not so welcome) GUESTs are. But if I read a sentence like

All of the people who represent me in my government have been bought and paid for by the "Israel first" lobby.

in Mudcat I start seeing a shade of grey in the continuum from white to black. Jews bribe and pay to control the world was a topos (used by very honourable people with the best of intentions) in the Germany of the 20s and early 30s of last century.

I have read other and worse sentences of a similar type and always shake my head in disbelief that no other Mudcatter from the left part of the political spectrum seems to notice what I see.
