Save yourself some sanity dahs and just block bis like everyone else did. He's trolling.
So "trolling" is the term you give to whoever refutes your points and defeats you in an argument or debate? Interesting.
You haven't blocked me. You just admitted defeat and ran away like you always do. Then later you'll come back crying like you did the last time.
"I know I took my ball and went home in a huff when I was beaten, but now that I think about it I want to give it another go. So can we please re-start the debate now that I've decided I do want to play? I promise I won't be a little ***** this time and will actually try to defend my own position, no matter how badly you beat me again."
This is twice now you're admitted defeat and run away. Like I said, it gives me great satisfaction to know I got you to give up and admit you were wrong.
