you with the face mentioned this in another thread:
[QUOTE=you with the face]
Any time I hear a comment prefaced with a certain type of disclaimer, my spidey sense tells me to that whatever perceptions the disclaimer is intended to ward against are more than likely true.
– I’m not a racist/woman-hater/homophobe/anti-Semite, but…
– No offense, but…
You get the idea.

Is there a name for this kind of statement?
I have no idea what the answer to the question is, but I think your example and the quoted one, are a bit different.
In the quoted example all it says is “I’m not a racist/women-hater, but…” Leaving it open for something like “I’m not sexist, but that girl is dumb as a brick”
On the other hand your example says "I’m not a ____ but all_____ are… which narrows the field down to something such as “I’m not sexist, but all girls are dumb.” Which makes it more likely that the speaker is whatever their about to claim their not, or at least closer to it then they think they are.
I know that’s most likely irrelevent, at least to this specific OP, but I’d thought I’d mention it.
Grr! Curse you for your accuracy! :mad:
Then…answer what I meant, not what I said. Does that make sense or should I just scrap the whole thing?
Well, I’d call that kind of statement “hypocrisy.”
It can be hilarious when used ironically.
“I’m not a man prone to swearing but Jesus titty-fucking Christ that shit is cold!”
To quote Mike from The Young Ones"
“I don’t like to say anything negative, but No.” 
Let’s coin a phrase:
hypocritical qualifier?
