Wow you have a short memory if serious.
Some of the names I can't remember 100% because the search only goes back so far (Dec. 13/2015 [example: I couldn't remember the Muslim debating TheseTwoHands in the Questions for Muslims by Squeezewax]):
Here's a list that are anywhere from certain to likely (even though some deny it):
s karlyle
Gervinho
m25105
farFan
fanu
smashmarxism
Luger (yes I'm putting him on that list because he is one of the primary apologists and shares common hates - Israel and the US)
kinOmega
Leagon (I don't buy his shtick for a second - that he was or is a Christian?)
Grimballer
Ruprecht (I just don't know what to believe about this guy - he says he's a Christian but he mostly apologizes for Islam)
spin_ (Muslim apologist, Israel hater)
sadclown - I don't buy that he's not a Muslim as he's one of their most loyal apologists. Also hates the US and Israel.
Quipling - muslim apologist, Israel hater
Banned poster: HollywoodNicky (worst of the bunch), liquidfire
Israel hater I haven't seen for awhile: Rod1
incomplete list but this took no more than a few minutes. Of course Leklok is on there too.
And that's over 10.
Not to mention former-Muslim (is exmuslim the same thing) Psych Major
