So many things that we all grew up knowing were wrong (and mean-spirited), and not to do them should not be joked about.
Now, if you use the wrong pronoun, or say you like the Prez (or don't), if you are conservative, if you believe in the founding documents of this country, and who you work for ... anything can suddenly become a war, anger, attack, and demonstrations with edgy violence.
This reveals a serious lack of sanity, self-control, and they are passing it on to their children ... creating a new generation with the same insanities.
I fear for my grandchildren and great-grandchildren (2), and the world they will live in. It is up to us to teach them that the war-talk, the hostility has to stop. We can agree to disagree. One side believes you can bully people into going their way. Don't agree with them, watch out.
That will back fire on them, and their kids may just turn on them with a new goal, a new concept, a new agenda. But they will have been taught to use anger/violence/screaming/ pushing, and not letting anyone else say differently.
It will back fire on them eventually.
