Sports on TV is a total waste of air time... sports is a social thing you do with friends to keep fit... "they" have turned it into something that divides people within countries and between countries that requires no effort at all... just sit on your arse and yell at the screen. At the end of the game you feel good because someone else ran around a field for an hour or so and beat the other team at something... what a total waste of time...
The difference between you and I however is that I would never demand they ban either.
I agree, sports on TV is a waste of time, and like you I don't believe it should be banned simply because I don't like it and don't see the value in it.
However, with porn, I truly believe that it is indicative of a sickness and I see porn as gnawing at the foundation of society. I am not alone in this; there are many psychologists and activists on both sides of the spectrum, right/left, center, even feminists, who believe that pornography is harmful. But just because a lot of experts support my view, does not make it valid. I do not seek to make an "appeal to authority" because that is all too easy and there are competing authorities on the other side who will say the opposite. Perhaps I am wrong, but I believe the evidence is in my favor and we can look back over the last 50-60 years and see that pornography has contributed to damaging Western society.
As for sports, the only sports activities I will ever watch on TV are MMA because I train MMA/grappling and I have a decent understanding of what is going on and can relate to it on some level. I hope to one day get into the cage in the amateur circuit but that might be a bit down the road for me.
Other than that, I don't see the value in watching baseball or football, unless you play baseball or football and are trying to gain insight into how professionals handle things. If you are not involved with some sport, then watching sports on TV is essentially an attempt to live vicariously through others.
Americans would be much healthier if they would get off the couch, shut off the football game, and go form a local football team with their friends and co-workers, their team could face another team from another factory/plan. Heck, they'd be better off if they just turned off the sports and went outside to walk, jog, run, hike, bicycle, or anything.
But as you said, failing to see the value in watching sports on TV doesn't mean we ban TV. I agree with that sentiment and I would not ban something just because I don't like it. For me to be in favor of banning something I would have to sincerely believe that it is incredibly damaging to society and detrimental to the development and progress of the race[volk]/nation. I believe pornography fits my criteria for banning something.
