Booing kids not becoming of adults

I vividly remember watching the BCS bowl in January 2010, i also VIVIDLY remember losing to Alabama 37-21. Being a die-heart Texas fan, I was infuriated! That year, i noticed this freshman name Garrett Gilbert. Although that game he wasn't doing so well, I was like "Hey, he might be pretty next year." Welp, it's next year, and I'm still not impressed. I went to UT vs. Rice September 3, 2011 SO pumped up I was ready to go and watch my team eat Rice alive.. Halfway through the game I wasn't so sure we were going to take that nights win. "Take Gilbert out!!!!!!" kept coming out of mine and all the other fans mouth. A week later Texas vs. Brigham Young University had me biting my nails. Gilbert continued to disappoint me, he makes me mad.--
Now I read this Editorial from the Austin American Statesman dated Tuesday September 13, 2011. "Booing kids not becoming of adults" Basically it was saying that fans are being to harsh on the UT football players, specifically talking about Garrett Gilbert. What?
"We understand sports, in general, can be a pleasant escape from real life. But we also believe sports should not be an escape from adult behaivor." 
"...It seems also to be taken for granted that adult behavior at University of Texas football games at times is beneath the level at which adults should behave." I have to disagree with these two statements, I think it goes to far to say that fans aren't acting like adults. Yelling isn't anything out of the ordinary at a football game. We have the freedom of speech and unless anyone is physically getting harmed, words are only words. I think this writer intended UT football fans to read it, maybe to tone it down. And I mean of course there are  times when people get into fights, and there are times when people get to drunk, But the writer chooses to defend theirself by saying that the crowd booing Gilbert is an act of childness. It's just not a good arguement.  I think the writer is forgetting that we are not talking about five year olds, we are talking about grown men who partake in a competitive sport and run over each other. The players know what is expected of them and they know the things people will say if they don't deliver. This is a dog eat dog world. Everybody gets critiqued, everybody gets judged. I just don't it is really a big deal to the players, this is football ya'll! If you can't handle the heat get out the kitchen!
