I have come to hate the usage and twisting of the word "discrimination," because discrimination is something we are free to do and should do every day (not discrimination against blacks per se, but discrimination between what we want and what we don't want - kind of what freedom is about).
Thoughtful discrimination is OK, but prejudice against anyone, not for what they do but for who they are, can be irrational and hurtful. Ron Paul? Maybe a prejudice problem with blacks.
We know that his positions on foreign policy and his somewhat unhinged behavior when he talks about it are fairly loony. He comes across as unpatriotic about 9/11 and his reported anti-Israel position stinks.
Buh-bye Ron.
