To circle back to the OP.... the discussion was supposed to be about:
"how Islam has become synonymous with terrorism this past decade."
Frankly, nothing about the middle ages, inquisition, drone attacks, etc. have ANYTHING to do with how the public perceives Islam or why it has 'become synonymous with terrorism.' I really think I answered it in my OP... the reason the American public draws that conclusion is obvious. For the past decade or so, every single major act of terrorism committed indiscriminately against the general American civilian public by a religious group/fanatic/zealot has been done by a MUSLIM person.
This isn't debatable. There are no Jewish, Christian, Buddhist, Hindu, etc. fanatics who have attempted/succeeded in multiple act of indiscriminate mass murder of American civilians.
It also isn't debatable that the only religious group with organized terrorist cells who aim to regularly attack the general American public do it in the name of Islam.
It also isn't debatable that 99.9%+ of Muslims are not terrorist.
But it's frankly a really stupid question/discussion to have on "why" Islam = terrorism to the general American public. The answer is obvious. The minute Westboro Baptist Church starts blowing up buildings or committing mass murder "Baptists" would also get associated with terrorism. It doesn't matter if it is "wrong" or "ignorant" or even if you think Muslims are "justified"... it is what it is and it won't change except through time... time in which American civilians aren't targeted for mass murder by people who claim to be doing so in the name of Islam.
