> If I say "Christian Communities hate gays", you'll probably think of one or two specific communities.
That might be true for me, but I'm thinking of "Protestant Christian evangelicals and co." as one community, so...
No, if only to make a point.

Yup. What I expected. I'm positively full of bias, and happy to admit it.
The clear subtext in your examples is "Jews" (not "some Jews"), "Muslims" (not "some Muslims"), "Christians" (not "some Christians"). A racist (or variant thereof) will not say "all Jews"/"all Muslims"/"all Gays"/... , they'll just casually namedrop "Jews" (or even a single Jewish personality), "Muslims" (or even a single Muslim personality), "Gays" (or even a single Gay personality), and use this as a dogwhistle.
Also, please do not make assumptions on my biases.
Now, transpose this to human beings. The message we're commenting is a warning against Jewish Communities, i.e. I can't think of any reasonable way to interpret it other than as antisemitism.
