re: Ah, Jeez, they're debating 'consent'

No, its a legit question. At what point do our preferences stop being prejudiced and just start being our preferences? Is the line strictly drawn at sex? Friendship? Where is the line drawn? Things like this are important to know when people make laughable statements such as "you're transphobic if you wouldn't date a tranny." If I said I prefer not to frick black girls (I actually prefer black chicks in general) is that racist? Or is it just preference?

ETA: I knew neither of you would be able to answer this question even though your ideologies are consumed with obsessing over discrimination and prejudices.
