@Mountainlady16: They are holding an event, as part of a ongoing campaign, to promote peaceful co-existence. Perhaps this is something the peaceful church you belong to, should understand.
So far, here's what I see:
1. A group of people, namely, the Muslim community, is hosting an event to promote peace and co-existence.
2. A deranged, mental health patient, on drugs and alcohol, using religion as a crutch, who killed five armed forces services, and was killed himself by the police.
3. You, who claim to be peaceful, but you're here, fuming against a group of people, whose only crime is that they invited the community for a peaceful gathering, pulling rank, by saying that your ancestors have been here longer than everyone else, and calling for hate against those holding a peaceful event.
4. You're hollering that the US is a Christian nation.
I can only assume that you're getting your education, at your "peaceful" Christian Church, but are you starting to appreciate what this is looking like?
