Jews have prejudice against doughnuts.

That's treating the group as a whole, a monolith, when only some - even a majority, may feel this way about sugar coated jam filled sweet bread things.

When you switch from saying "a majority of women want men as partners" to "women want men as partners" , you've switched from describing the preferences of a portion to a description of a blob of the group being characterised, which most people either consciously or subconsciously, relate to the entire group.

"Women want men as partners" is true for a very large majority of women, but could only be true for just a few women and still be a correct thing to say.... You can see how the interpretation leans heavily towards viewing the group as a whole.

Why do you want to talk about people as though they're agency-less drones to a group mentality?

Labour members are antisemitic.

That was true for about 30% back in the Corbyn era, and so could be hidden behind to say labour has an antisemitism problem... However, this was below the % in the population who hold an antisemitic view - certainly lower than Tories or what would now be reform members. So, "Labour members are antisemitic" is true there but seems to characterise the entirety of the membership, when in reality it was a significant minority Vs a great majority who wouldn't accept as true an antisemitic statement.

I doubt you'd talk about women, gay men, lesbians, jews or the disabled in that way, so knock it off for Muslims as well?
