In my lifetime, absolutely.
I was born the day after Kennedy got shot. (In the 1960 presidential debates, Nixon and Kennedy contemplated a joint campaign tour, at which they would both appear at campaign events, debating policies. Would this be conceivable now? Any Democrat who considered such a plan would be threatened with "being blown up" by Madonna.)
Since then, leftists have continued and accelerated their downward spiral.
Recently the right has started to punch back, after decades of being the civility punching bags.
Leftist take great umbrage at being treated the way they have treated their political opponents. "That's not the way the game it supposed to be played. We're supposed to be complete jerks, lying, fabricating, employing innuendo, and employing a completely different standards to leftist a-holes, and you're supposed to just take it."
Trump is the result of that.
Get used to it, leftists. You created him. Enjoy.
