If you say all lives matter, you can now lose your job because many have for saying it.
We are entering a time of PC fascism where just thinking something contrary to Left wing ideology will destroy your life.
Another example are the Left winged college compasses across the country. Denis Prager did a movie called, "No Safe Spaces" where he documented the Leftist intolerance. Students now declare "safe spaces" on colleges all across the country where you are not allowed to express certain politcal stances, specifically, conservative political stances. In addition, professors are often canceled if they are deemed impure from a Left winged perspective. For example, a professor was canceled for merely referring to a conservative perspective but not actively promoting it in any way. She was a life long democrat and considered herself "woke" but cannibalized by her own. Another professor had a similar situation, only, his life was threatened and he lost tenure and fired. He later went to court over it and won. And I'm sure we all have heard how conservatives are denied the right to speak at college a college campass all around the country.
The Left is essentially preparing the next wave of leaders all across the country so they will continue to fight, such as we see with Big Tech censoring conservative thought on things like Twitter, Facebook, Youtube, etc. In fact, Youtube used to have a trailer of "No Safe Spaces" but took it down.
It is akin to Nazis burning books in years of old. It is about censoring material and thought that runs counter to your own and ideas that you have no way of successfully countering.
Nazism and Marxism are very similar
