Is it true The Cosby Show changed attitude of americans?I heard The Cosby Show eradicated racism against black people. I LOVE that show, its so funny. Now, we have like a muslim version of that show. The name of the show is called "little mosque on the prarie". That show is AWESOME! So hilarious. For years people have been saying that muslims are terrorist, or that their wives are treated as 2nd class citizens(btw im muslim, so I know that's not true) and that show is slowing breaking down the stereotype within ppl. US has comfirmed that they are making their OWN version of the show, just like they did with the office. But whateva. What are your people thoughts on The Cosby Show?
