Agreed. I'll only add that parents of schoolkids have an unwritten but understood obligation to not say everything they're thinking on Facebook. While I've never deleted a thread due to someone's dissent with what I've written, I *have* disengaged many times. My son has made it clear that the truth I dispense is sometimes embarrassing to him due to the liberal cesspool in which we live. Students can face retaliation due to what their parents say on Facebook, and none of us want that to happen.
(There was this one time when two of my son's teachers joined in to argue with me about my claim that teachers are not as underpaid as people think due to their having 3 months off per year. It practically killed me when my son asked me to stop because he thought either the teachers or his peers would be mad at him. Grrr. It still bugs me but I did indeed eat crow by clamming up and letting everyone think I was wrong about teachers being paid as well as the average American if you just consider how much time off they get. But I digress...)
So, I can see why Joe stopped talking to Jaime after twice making his point. Beyond that, Jaime isn't going to learn anything anyway. In her hatred of those she calls "haterz" she is, herself, a hater blind to reason and logic.
