a) Yes.
b) Yes.
c) No. Racism is racism. It's not "reverse" racism. It's racism.

There's no reason to think the other two don't exist.

I understand racism and reverse racism to you is a sore subject, right :confused:?

I believe reverse racism exists.

"Racism consists of ideologies and practices that seek to justify, or cause, the unequal distribution of privileges, rights, or goods[citation needed][/sup] amongst, or otherwise exhibit hatred or prejudice towards, different racial groups."
— Wikipedia

Does the phenomenon which is named "reverse racism" really "consist of ideologies and practices that seek to justify, or cause, the unequal distribution of privileges, rights or goods amongst"? I'm not sure it does. So, I think that "reverse racism" is an incorrect term for the phenomenon.

Heterophobia? o_O I can't even imagine that.

Misandry exists, but I don't think that the misandry is just "reversed misogyny". These phenomenons are some different.
