@smartz: I see what you did there.
@Dog Legs:
>>Don't see what's fundie about this quote. <<
Near-total ignorance of the practices of another religious group and outrageous accusations without any basis in fact.
>>Muslims are are often inbred, as they frequently marry their children off to first and second cousins.<<
Citation needed.
Cousin marriage may happen at greater rates in the Middle East and over to Pakistan than elsewhere, but you would have to prove that the level of inbreeding there is statistically meaningful outside of small populations that are relatively closed (e.g. some immigrant communities in other countries). Second-cousin marriage is close to a non-issue in terms of genetics; fertility actually maximizes with third-cousin marriage (http://en.wikipedia.org/wiki/Cousin_marriage).
Also, cousin marriage is relatively uncommon in Indonesia and Malaysia, which have very large Muslim populations.
>>Devout Muslims can also have a noticable mark on their forehead<<
Yes. That's callus from contact between the forehead and the prayer mat. http://en.wikipedia.org/wiki/Prayer_bump.
>>it's not totally implausible that this may cause slight brain damage.<<
Yes, it is totally implausible. The velocity involved is far too low. You might as well as that doing push-ups every day causes brain damage, or that wearing glasses does (I have calluses from my glasses' earpieces).
We will call out fundies for being fundie even when they are making fun of other fundies.
