offended and ridiculed me 

I attempted to reach a consensus with , but he ridiculed me: 
"and much less "CNN talks about it". Oooooh, I'm impressed! ) What kind of an argument is that, "CNN talks about it"? hahahahahah"

Someone who makes this kind of comment doesn't want consensus, he wants to his way no matter what.

 has also offended and ridiculed me other times:
"Are you mentally challenged?"
"Now go watch the fireworks in Copacabana and stop crying, Mr Carioca. )"
"Man, you really are a nut job! "
"Get a life, carioca"
"EconomistBR is the one who is being intolerant" 

No user in Wikipedia has ever offended me so much.
