I'm seeing a disturbing theme in this thread, in which people are suggesting that there should be less, not more, free speech of a controversial topic. With all due respect, that's the kind of thing you see in totalitarian governments like Stalinist Russia or Communist China, where governments try to suppress freedom of expression in the misguided attempt to increase stability. What is needed is MORE speech, not LESS.
I encourage defenders of Johnson to fully and wholeheartedly throw their support for his continued employment at Tech. I also encourage the opponents of Johnson to fully voice their opinions on why Tech should go in another direction. A full airing and debate of a controversial topic is the only way that a good solution can be arrived at. Suppression of dissent (either side) only leads to resentment and discontent.
I also want to address this concern I see raised from time to time, that it is "damaging" to have "coach firing" discussions in a forum in which recruits and their families can see the debate. Not only is it okay for recruits and their families to see debates on the coach's future, but morally it is the right thing to do, to let them know that there may be a question about the future stability of the football program. If you are trying to sell your house, you are morally (and legally) obligated to let prospective buyers know if there are any structural, plumbing, termite, or any other issues that they may need to be aware of in the future. If there are any questions whatsoever, even if you think it isn't a problem, you MUST let the buyer know. A similar obligation exists with respect to recruits coming to a school. If there is some doubt as to whether the coach's job is on solid footing, it is immoral to suppress that knowledge from the recruits and their families by censoring discussions in public arenas among the fanbase about the coach's future.
Finally, I want to address the concern that discussions of this sort only have a place at the end of a season, not midseason. This is nonsense. As anyone who has followed college football knows, it takes time to build momentum for a major change. Public opinion can't be changed overnight, with rare exceptions. If a debate is put off until after a season, then it may be too late. There is not enough time for a debate to start, for momentum to build, for pressure to be applied to the administration by donors, and finally for action to be taken by the administration. The coaching carousel typically happens right at the end of the season, and if a school isn't ready to act, then they'll be left in the lurch. The debate needs to happen during the season, so that when the season's end comes, enough momentum will have been built up that the administration will have public backing to take action.
Bottom line is that more free speech is never the wrong answer, as long as ALL sides of an issue are free to add their opinions.
