What I mean is that when you combine virtually any idea and power politics someone will find a way to justify violence in that ideas name, no matter how hypocritical it may seem.
I suppose we could say the word "ideology" might be the solution. As often noted, the 20th century ideologies of Communism and Fascism arguably caused more deaths than all the religious wars prior. That in no way takes away from the fact that religion does have a lot of violence to answer for.
It's mankind's habit of searching for some perfect idea of "truth" which is then defended fanatically, that tends to combine with our species' innate aggression to create wars across the centuries.
I stick by my words from way back in the thread. Combine anything and politics (or I suppose just power) and you get conflict and violence more often than not.
