There's that word again... that 3 letter word, "but". Not butt, but "but".

I'm not an asshole, BUT...
I don't hate gay people, BUT...
I'm not a racist, BUT...
I consider myself a liberal, BUT...
Some of my best friends are Hispanics, BUT...
You know I love you, BUT...

What it really means is "Everything I said before this little word is a complete lie."
