people hate Muslims because of 911, but if the terrorists were Irish would people hate catholics?

Question

after all islam is just a religon and not all are radical

Answer 1

There is an enormous difference.

The Muslim terrorists claim that their religion teaches them to be terrorists.

Irish terrorists make no such claim.

Answer 2

Every muslim is not a terrorist!
But the issue here is that its not geography that's hindering.
Its their claim to the religious right(Jehad) to kill others is what is resulting in the negative opinion.
