*See? I get get away with BS qualifications too.
Just because you would prefer to assign qualities to ideologies based on practicioners of those ideologies doesn't mean that doing so is correct. Any nuanced view of politics would maintain that qualifications in these circumstances are entirely appropriate. Nietzsche was no more responsible for the Nazis than Marx was responsible for what Stalin did, or that the prophet Mohammed was responsible for the 9/11 attacks.
So I'm not really sure what your point was, aside from a deliberate conflation of fascism with Nietzschean ideology. It seems like you're railing against something I didn't say.
Apologists of all stripes love to claim that any horrific real-world implementation of their pet ideas was because it was somehow perverted or otherwise compromised. Communist apologists in particular are extremely fond of this particular example of the Scotsman Fallacy (http://"
http://en.wikipedia.org/wiki/No_true_Scotsman") because it gives them a chance to bloviate about the wonders of their particular brand of communism. If there's anything communists are good at, it's endless bloviation.
As I said in the second post in this thread, and as most of the responses have shown, attributing violence to any particular ideology is a shaky exercise. The Old Testament specifies in Exodus that "Thou shalt not suffer a witch to live," and yet somehow modern Jews are able to rationalize this particular injunction from G-d away and have not been particularly enthusiastic about witch burning of late. Even people with a religion that
explicitly encourages specific forms of violence are somehow able to ignore that when it doesn't seem worthwhile. Meanwhile, Christians in Nigeria are lopping off the hands and feet of children they think are witches.
So, to answer the thread's question succinctly, people from different religions fight against each other because people fight against each other, and sometimes the warring factions happen to belong to different religions.
