You mad bro?
This site has a bunch of members that don't rematch.

This site should have an algorithm where when someone whines about not being granted rematches that they are automuted. No one is obliged to feed your bruised ego.
Maybe, believe it or not, they have something else to do? During that last game someone rang them up to talk to them. Maybe they said "oh. Wait a minute I'm playing a game" and don't want to keep their caller for ages?
Maybe their limiting their games each day?
Maybe they didn't enjoy the game?
Maybe they had already started a new match?
Why should they have to rematch?
I mean if you lost and ask for a rematch. I will rarely ask for a rematch if I won. Almost never. Only if me and the player talked, agreed before hand, or it was a very fun game.

Do you accept EVERY rematch someone challenged you to? Every single one?
Maybe try okay unrated a bit more. People will accept rematches a lot more on unrated.

Since I would imagine 99.99% or more of all players that play here are not professionals, I don't see how your statement applies.

well mickynj, You are the coward here. If you lose a match then its your fault, asking for a rematch just to try again doesn't mean that you will win and the rematch should happen because both the parties are interested not just because you want a second shot at it.
If you blunder, then that means the other player has perseverance and you don't. so stop complaining and work on your skills.
You should probably stop playing chess as you cant handle the ups and downs of it.
This site has a bunch of members that don't rematch people. This site should have a mandatory one-game rematch. Especially in blitz chess. They win by one second and are too scared to rematch.
