Had a long discussion with someone about Muslims, and he pointed towards FGM (alongside other instances of institutionalized misogyny) - saying that a culture that promotes this is inherently bad.
He dismissed all my arguments as "radical egalitarianism".
I've faced this kind of thing in a number of places, both in real life and on reddit in particular.
Criticizing FGM and misogyny in certain Muslim communities, certain aspects of Roma culture, and more commonly "problematic" elements in "thug culture" (or "ghetto culture").
Most of the time people with these arguments pose as reasonable critics of a specific culture, and say that they are not racist. They aren't just saying something like "I hate <color based slur> people culture" - they point to very specific issues with a certain community as the basis for what they say.
So to be clear it's "I don't hate [marginalized group], I just some things about [marginalized group]." - and the "some things" list is fairly large.
How do you argue with this sort of thing ?
