Let me chime in and say that if you have to ask if you should be offended, then you shouldn't be. It makes you sound like a fence-straddler that has no opinion of his own and wants to form an opinion based upon the majority.
Why would you be offended? Should every commercial made show Africans, Jews, Palestiniants, Americans, Dominicans, Cubans, Asians, Irish....
WAIT! That would be a long commercial, wouldn't it? Are you offended when you see a Tide commercial and it only shows the white housewife?
Why don't you grow a brain and fvcking use it? You obviously have no logic, no capacity to think rationaly and critically, no ability to form opinions.
I believe P&N is calling you. Both sides would like to recruit you as a passive yes-man.
