There's no 'hate' on my end. I just came from the school of words and actions have consequences. Those a little younger than me with kids have babied and coddled kids up through this age, if not longer and has made these kids unbearable. Making excuses for these kids is why they grow up to be entitled punks. Acting like you are above it all is actually worse than holding these kids responsible for their actions. Hard for me to have the ole 'aw shucks' or 'kids will be kids' when I know 18 year old kids past and present getting shot at doing something way more important than chunking a pig hide around the football field. It's more than football. It's about life and teaching people respect. If you don't get that, then maybe you need to grow up and look at yourself in the mirror.
I understand respect and I understand actions have consequences, but singing a 'Bama song isn't exactly how respect and consequences should be used. He owes this fan base nothing. Literally nothing. If anything he needs to answer to his father, if his father even cares. But all of us, he doesn't owe us anything. The "respect" and "consequences" you speak of make is appear as if he owes us something. I'd argue he doesn't owe us anything, especially given how a large quantity of this fan base acted before during and after his signing with UGA.
I know Tennessee, Auburn, and LSU fans that have all sung Dixieland Delight and said, "that's pretty dam catchy." This is just my opinion, but sure seems like folks are looking for reasons to hate a kid over something absolutely benign.
