Hi, Buzz.
The unfortunate truth of the world is that any idea --- good, bad or neutral --- is likely to be misinterpreted, miscontrued, twisted or otherwise used for bad purposes.
Do you agree that there are also some people who have done some pretty horrific things and justified them through Christianity?
People have justified some pretty hideous and stupid actions through conservatism, liberalism, science, religion, atheism, evolution, creation, capitalism, communism, socialism, etc. If we start marking off philosophies and ideas because somebody used (or abused) them to justify wrongdoing, we'd quickly find that there wouldn't be any philosophies or ideas at all.
