Their religion is not germane.
To me, and most of the sane western world, ones' religion is "germane" when said religion is routinely used as an excuse to commit atrocities. Especially if one does not denounce said atrocities.
So, do you know, does the mosque in question denounce such use of their religion. If you do not, that's fine, I couldn't care less if you know or not. I was asking the one who brought them up simply because I believed I would be more likely to get a ready answer from someone who has direct knowledge of the mosque. A belief that, apparently, was ill founded, seeing as you still have not answered as to whether you even know. If you do not, simply say, "I do not know.", and I will seek an answer elsewhere. The fact that you refuse to answer the question suggests that you know the answer, and believe it will not make them look good. So, please show me I am wrong. I beg of you, show me I am wrong....
