So political activists realised they can brainwash or pressure idiots by claiming that any opinion, person or class of people they don't like creates "lack of safety". It's a kneejerk reaction: safety first.
The worst case I saw of this so far was an event organised by my workplace, for teaching programming. But straight white men were banned. If you were a white man you had to show photos from Facebook to prove you were gay. The justification for sexism and racism was stated as creating a "safe" and "collaborative" environment. Implication: straight white men are unsafe. Except when they're teaching, of course. Then they're needed, so stop being unsafe.
There's nothing new about this sort of abuse. Orwell focused on the way leftists constantly manipulate language in 1984 with the idea of Newspeak. Consider the contradictory term "dictatorship of the proletariat" or how every communist country calls itself a People's Republic despite not being a republic, nor run by/for the people.
