a major necessity of racism or bigotry is to COMPLETELY ignore accomplishments of the group you're biased against. if the people who slam blacks and muslims stopped using inventions by those groups, their lives would be much more difficult. once again, racism isn't rooted in an intelligent or accurate idealogy, it's simple-minded in it's belief that an entire group acts/behaves/thinks/etc... a certain way. there is often little logic and very few facts involved. i've noticed that in most forums, when i begin posting statistics that disprove ignorant ideas, the conversation either ends, reverts to personal attacks, or continues with opinions that have already been proven incorrect.
