just read the tl;dr

"but OP, that's islamophobia"

No, it's not.

islam is a faith that is centuries old, and like many other religions was created in a time when man understood little about the world and the natural processes that occur within it. 

This in itself is not an issue, the issue is that unlike many other faiths, islam has failed to modernise with the times, even the catholic church will admit that the big bang created the universe and that evolution is the process that god created us through, but islam has consistently refused to modernise and has even actively punished those who tried to do so.

so OP, what the fuck does that have to do with isis? simple

the islam that isis practices is the same islam the prophet muhammed practised. The destruction and execution of people who won't convert, the destruction of non islamic art and architecture for promoting idolatry, the "marrying off" of captured women and children as rape slaves and "wives" the buggering of young boys, all done with the complete and total blessing of allah.

But OP, you're a white male in the west, what would you know about islam or the people's who lived in that area of the world?

I lived there since i was 3 weeks old, and only returned to the west to start secondary education at a boarding school. I've spent my entire life being told - mainly by the locals in the areas we lived - how dangerous it would be to go too far from the house, how this group on this street would come after me if they saw me, what they'd do to me.

Hell, when we lived in iran my house was molotoved twice on the anniversary of their islamic revolution, which surprise surprise turned the country into a theocracy and thoroughly rinsed the country down the shitter.

and one more point, here in the west we have freedom of speech and discussion; we can question and challenge any ideology we want without fear of reprisal. I'm not being racist, because Islam isn't a race, it's an ideology a set of ideas and beliefs and nothing more. If we're not allowed to question, to point out contradictions and stand up for our own beliefs, we're no better off now than we were in the dark ages when the catholic church burnt scientists for heresy.

tl;dr the islam isis practices is the same Muhammed practised
