Misread the post. Thought he was saying "What he (Gahlee) said [was the reason] is all I know." And no. Not retarded.
This is incorrect, in that GahLee did not confirm whether he was a free thinker, but rather asked for float go define the term that GahLee had just used. He may or may not be a free thinker by either his own or float's understanding of the term. But yes, he was banned and unbanned, in a surprisingly undramatic fashion for each.
GahLee asking for float's definition suggests that GahLee may not actually be a free thinker, but that's just me.
