Pathetic members preventing people from participating in conversations

I rarely post anything because i do not really understand why you would chat on a chess site, but i see that some people spend a lot of time on it. What surprises me is that a person called Hessianwarrior blocked me from a tread about nothing. It is pure racism against citizens of luxemburg in my opinion and i would like to know what the reason is. Is it normal to not even mention why you do this? I’m in a hotel and quite tired but i would like to understand more about how members treat each other badly here. 

He did that to me once, too; over writing and performing a song just for him.  Effort then blocked.  He acts big and tuff and yet is a complete baby brain.  He likes to be in a public place buying cigarettes and lottery tickets yelling aloud into his phone "blocked" and people quick look to see who the heck is so important.  Uh not him.  Forum dwellers avoid chess...gotta study first they say then don't do that either
