So, we have a case of someone feeling they should mow down a group of muslims praying, and why? Presumably because it was muslims that did something nasty last time.
This logic is terrible, and if you follow the same logic forward, the logic used for all race and religious hatred, you must now panic at the sight of a white van man!
On my drive right now, we have two of them (carpenter and decorator), so that must be terrifying to the neighbours!
If people can see that such a comment makes no sense, how can they not see that such comments about muslims or any other race or religious group are just as daft.
