No wonder people from the rest of the world does [sic] not know our national anthem when even Americans don't know our national anthem from a patriotic song.
So no wonder people here in America does [sic] not get it or thinks that it is no big deal.

Even some of our Politicians does [sic] not know what our national anthem is from a patriotic song sung on the 4th of July.
You should really learn English if you are living in America. It's in your own best interests.
Do you realize that does not is the same word as doesn't? One is just a combination of the two words. Just like do not and don't.
Does not is proper English.
It also depends on what part of the country you are from, here in America.
