Since the Crusades were brought up then we have started this wonderful history lesson, why stop at the Crusades? Let's go back even further!

It's ridiculous to talk about what happened 2000 years ago, 1500 years ago, 1000 years ago even 200 years ago. None of that matters now because today is today. What happened, happened. This is not a tit for tat situation. Who the fuck cares. There is a radical element, regardless of what religion it is, that needs to be halted. How? Nobody has a clue because everyone is far too busy arguing over whether or not it's politically correct to talk about what issues may or may not exist.
Just the other day the Paris Grand Mosque Chairman came out and said hard, military action needs to be taken against ISIS. This was nice to hear. What was not nice to hear was what else he said, in bold:
Paris Grand Mosque chairman backs fight against ISIS - CNN.com
In his own mosque he is being told that he doesn't represent Muslims because he is not radical enough. This is a problem for everyone. It doesn't matter what the Christians did, it doesn't matter what the Muslims did, it doesn't matter what Russia did, United States, Iran. None of that matters. What matters is we identify that there is a problem: mostly young radical Muslims that need guidance. They are getting their guidance from ISIS fruitcakes that are feeding them drugs to keep them high so they can control them and kicking them cash from oil.
Okay, carry-on, back to work for me. You guys have fun arguing over whether or not there is a problem and who's fault it is!
