Welcome to the Internet. This rant of yours doesn't make you any better than they are.
What kind of disgusting scared people are those who talk trash in a game and then block you
Well for a start I haven't named the player in question (I could), but I am not going to. Also wanting to discuss the psyche of the trash talk and then block before a response coward is not the same as actually trash talking during a game.
I am not laying claim to be Gandhi, but there are subtle differences I think you will notice.
The cowardice on display sometimes is pitiable. They like to talk but are so sh!t scared of a response that they block you. When I meet such a coward during chess, I really pity those supine spineless living breathing wimps.
If online talk scares them so much, just picture how they go through their daily lives. They should do something about their cowardice and grow some balls.
