"Maybe"

[Scootaloo]

First off... let's not kid ourselves... everyone in this country is racist. To some degree or another, we've all been raised in a cultural stew of racism. Now, how we respond to this fact is telling. So are actively racists, others try to pretend they aren't, and then there are those who are actively anti-racist. Plenty of overlap between these groups.

Homophobia's roots are in sexism - every homophobe you meet is also going to be sexist, it's an absolute guarantee. After all, Homophobia is based on "proper" gender roles and behavior.

So is there major overlap between sexists / homophobes, and the openly / latently racist sorts of people? I really don't have data. But I WOULD make a guess that people who are okay with hating someone on basis of sex, orientation, or race probably isn't going to be squeamish about hating people from any of those groups.
