There's certainly a lot of good reasons to quit a toxic job, and a lot of changes so need to be made, but it's gotten to the point where even the tiniest little smidge of discomfort is causing these people to throw their hands up and cry "Toxic!". It's absurd.
While there is certainly no justification for truly toxic work environment, life isn't all about participation trophies and coddling. Sometimes you just have to suck it up and deal with a little discomfort. Life is hard sometimes. Deal with it.
