If you set up an event specifically designed to insult/offend/antagonise a particular religion, you're always going to get a response like this from someone.
Please stop spouting nonsense...
Yeah, like those times when the Orange Order held their parades in Northern Ireland, celebrating victory in a battle over 300 years ago, where everyone had cake and ice cream went home with balloons.
No, wait, that's not right -- according to this for over 100 years people have been killed, seriously injured, homes and cars have been set ablaze, and bombs have been thrown around like footballs. In 1998, three brothers between the ages of 8 and 10 were murdered when their house burned to the ground from a thrown firebomb.
That was between two Christian groups and was over a parade.
