I personally can only see a single comment that was pretty much racist. The rest discuss the concept 'Islamic terrorists' - ie. those people who believe that they are following their religion by being terrorists. There is no implication, either direct or indirect, from me anyway, that islam as a whole is to blame - that would be ignorant and stupid. There are around 1billion muslims, that is a huge number of people to make any sweeping statement about. All this is about is the minority of extremists such as those that exist in most religions (such as Christian terrorists in the USA) and movements (animal rights terrorists).
What about any Muslim members we may have?
I don't know if we have any but, for example, I know we have others of 'different' religions here - how would they feel about this thread if it was pointed at them?
