Totally agree with your attitude on safe spaces. I somehow fear it's more than some nut-jobs finding issues with a statue or a flag. MSM is right behind them and amplifies whatever stupid idea they come up with. Look how colleges accommodate every crazy demand. "You're upset Trump won, here's your safe space, have some crayons, have a cuddle". I've never heard of a college taking a hardline approach, like we don't care you're butt-hurt by Trump's win, your paper is still due tomorrow. All these young (mental) liberals are actively encouraged to demand more and more - no wonder they take their fantasies for real.
As for re-writing history - I grew up under a Communist regime and most of the history we learned in school was fake. Decades later many people still believe that fake history they learned in school...
