couple things. Many of the same nanny crowd--the demographics skew significantly toward female, urban, well-to-do folks--drive the anti-hunting/trapping push, and those sports/hobbies/jobs are going down too. The US is becoming more and more an urban country (like the entire world). That means if you want to see the future, look at the values held dear in Manhattan, Chicago, Miami, Boston, San Fran, Seattle, PDX, etc. Yes, it is still a mixed bag but it is overwhelmingly liberal, wealthy, anti-"violence" in any and every form they can shake a tennis shoe at: hunting, football, hockey, etc. OF COURSE there are also 10000s of rabid fans of violent sports in many of those cities, but you get my point, right? The numbers are changing, and they're changing quite rapidly.
As we become more urban we start adopting urban values. Again, speaking mega-trends, stats driven. We can all think of exceptions.
Look at such cultural practices as corporal punishment (school and home), violence on the playground, etc, "Learning how to take care of yourself," etc. Watch old shows like Leave it to Beaver, Father Knows Best, etc., etc. in which it was simply routine and expected for the father to teach his son to take care of himself....Now imagine a similar show today.....the boy would be instructed to RUN TO AN AUTHORITY FIGURE IN THE SCHOOL, CLAIM BULLYING AND DUCK AND COVER! Preferably shrieking. Look at who dominates the nighttime sit-coms: males like Jerry Seinfeld, Raymond, the supposed guy in "Yes Dear," etc. We still have the odd exception (King of Queens as a modern redo of the old Honeymooners) but ever since the Alda model of the 1970s, males have been "De-testostroned" at an astonishing rate. And no sport across the country has been vilified more than football. Long ago, high schools and colleges had boxing teams. (Isn't boxing the only sport the cougs won a NC in?)....now how many schools have that?
There will come a time, after we are gone, that football will be gone. Unlike boxing, you need a LOT of people to have a football team....so we cannot eliminate football in the youth leages and HS and expect it will continue in college. Its days are numbered. Obama is the new man: effeminate, smiling, affable, non-violent, amenable, no principles that are not open to negotiation, apron-wearing, crying, empathetic, sympathetic, simpering. There is no place for football in that world. Sorry.
