I know they will. I've been to such religious days before. There is, however, an infinite league's distance between Christianity (of which I am a part) and Islam. I'm teling you right now that these people are breeding future Jihadis with these events. Besides that, there is nothing good about an event which has W.D. Mohammad speaking in it. Just read up on his incredibly blasphemous statements sometime, and you'll see what I mean.
Besides, sometimes it's simply wise to know what is happening around you, especially in such threatening and deadly times.
