Oh I see. So it isn't the religion or the beliefs that are a threat to them,
Sorry, is that a statement or a question? I do regard Islamic religious beliefs as a threat to non-Muslims in that they cause Muslims to engage in behavior that interferes with and jeopardizes non-Muslims personal freedom and physical safety. What about you? The fewer people who hold these beliefs the better. Don't you agree?
After all, freedom of religion could not possibly include the legal right to build places in which to practice that religion providing they comply with the local building code and town planning guide.
I can see why people who regard Islam as an irredeemably nasty religion - an attitude which you've stated above you're perfectly OK with - might object to having one of its places of worship located in their neighborhood. Can't you?
