You need to relax a bit, and you shouldn't get so emotional over what somebody says on the internet, especially when no offense was intended.
I was just stating the obvious, and you corroborated it yourself with your statements. Paes would have never reached the same ranking in singles as he did in doubles. Same for the Bryan brothers. Of course you need to be able to play tennis well. To me comparing doubles and singles in tennis is like comparing the Premier League or La Liga with the Austrian or Portuguese football leagues. Or like comparing the WTA with the ATP.
Now, all I'm doing is stating the obvious. No, I don't play tennis competitively, just recreationally. And I am not fat. You are way too emotional though. Maybe you should take synchronized swimming or something.
