Just reads as whataboutery to me. Sorry.The point I'm making is that those doing so have not repeatedly been called racists. Indeed the very media and politicians deliberately obscuring the difference between anti-Israel and anti-Semitism are often the ones attacking Muslims for not marching against terrorism.
I think there is a complete lack of balance in the attention given to this and I think it is political. Christ one of the breakaway MPs uses terms about funny tinged people and after 12 hours its put down to her being tired. The Goldsmith campaign has never been condemned by the Tory Party and the media pretty much schtoom about it. The suspension of racist Tory Councillors then let back into the party and not a dicky bird. If you can't see an issue here I don't think you're looking hard enough.
Its not that they are being weaponized by opponents but that they are taken as fact when those opponents mention them that I have a problem with. And the lack of Jewish voices on the other side is equally problematic. Jewish Voice for Labour get very little attention for example, but the conservative Jewish groups are taken as speaking for all Jews.
