I know you played, but the intensity of the internet is growing {even since 09- old dude
}. It's basically ubiquitous at this point. Students and family members who don't follow the games hear about what's posted. Having a little decorum doesn't stop discussions. All it stops is bloodletting.
Maybe there should be a basic rule, imagine everyone's dad or mom has James Johnson's dad's background and talent, but with a temper. If you aren't willing to say what you post to that person's face about their player son, don't post it.
