I think it is you who needs to learn English! look:

"you better learn English first.": it should be "you'd better ..."

"Some people just like to argue about every thing,” : it should be "everything'

"why you care?": it should be "Why do you care?"

"who care?": it should be "Who cares?"

Excuse me! This is English? Two short replies you sent, I can easily pick 4 mistakes from them. And you've got nerve to criticize others? Please!

So go back to an English language school to proficient your English before you upset others here!
