Drunk fans don't have kids? I know plenty that do.
Me personally, I've never been a fan of the whole "let somebody on the TV be your kids role model" thing. I'd rather see the parents stop paying cowards and actually be the role model themselves, but also understand that's probably too much to ask.
Regardless, it would completely shock you to find out how many drunk fans attend games and are screaming obscenities' in front of young children, including their own. Hence why a large contingent of people stopped taking their young kids to games a long time ago. I expect them to learn it all one day anyway, but I'd rather not spend my free time trying to explain to a 5 year old why calling somebody who just tore their ACL a "fucking pussy" isn't indicative of what a "role model" should be.
