My black/white difference/double standard I think is at least a bit more able to be proven than that there exists a double standard regarding making fun of Tebow.
With any person, whether in the public or not, there are going to be people who like you and not like you. There will be people that laud what you do and who you are and people who criticize you. That's not a double standard, that's just taste.
Some people like Tebow and those that do REALLLLLLLLLLY like him. Then there are people who don't like him and criticize him. Then there are people on television that get paid to critique people, like sports commentators. That again is not a double standard.
But when the standard is that when there is an unconventional running quarterback, almost all of which have been black, comes around you make a story about it and then go onto the next story but that when a white, super-public Christian running quarterback comes around and he dominates the sports horizon for an entire year even though he hasn't preformed any better or worse than those other black running QBs, that to me suggests that the white running QB is getting preferential media treatment and that a double standard does exist IN HIS FAVOR.
Most of the people who watch television and who drive ratings in this country are white Christians. That's just simple numbers. So the media gets a story that will appeal to them, and they run with it. Driving ratings in regard to certain markets is all about racial preference, unfortunately. Movies and television shows and even entire networks are driven by what race they are creating their product for because different races prefer different things, usually things that they can associate with because of racial similarities. That's Sociology 101.
So as much as you think Tebow is being given a double standard against him, I say he is disliked simply because there are going to be people who dislike you. But the manner in which the media trats him I think is definitely a double standard in his favor and should not be discounted by those who adore Tim Tebow.
