Greetings Sikh Zionist.
Glad you joined our forum. Welcome! I have met many Canadian Sikhs and they would all agree with your very relevant point. Islam is especially good at destroying cultures and peoples. The more tolerance one shows towards these fanatical people (and there is really no such thing as a liberal Muslim) the more chaos, anxiety and death accompanies. A Muslim is a Muslim first whether in Pakistan or Palestine...his sense of loyalty can never be outside of Mecca. The sooner the civilized world recognizes this fact the better everyone will be.
Shalom!
