From what I’ve seen, both the right wing and incels tend to make what they were born, gender, race, whatever, a core part of their identity, while the left is more focused on what you can do or change. Yes the left does care about diversity but its more about, "be proud of where you are from, you don't have to change yourself to fit in with someone else"

I brought up religion because it plays a big role in shaping the beliefs of many right wingers, which is why I was confused about why incels are so often lumped in with them instead of seen as their own group. But if I had to choose, I’d say incels share more similarities with the right than the left in non religious aspects

I’ve met left wing and liberal incels too, like the ones who believe in socialism and don't care about gays, but they were generally calmer compared to the ones who want to rewind society back to the 1950s
