Which was a response to the comment I was replying to, regarding distinguishing actual danger from everything else.
Danger, to me, means subversion of democracy and/or individual freedoms. Which means either a minority wilfully shifting the zeitgeist out of proportion with their strength of support or taking away people's freedom to participate in democracy.
It does not include everyone deciding to gradually change their ideals.
If the country as a whole is becoming more racist (to create an example), in terms of population percentage, then that's a structural social issue that needs to be addressed as such. Awareness of current news isn't going to enable one to address or change that.
More importantly, news gives you a mainstream perspective beyond typically dry work conversation or your highly selective filter bubble of personal relationships. What's acceptable to say amongst friends is not necessarily the same as what's acceptable in the mainstream.
You don't want to be the CEO who lost his job in the span of a couple of days because he didn't realize that anti-abortion stances are no longer publicly acceptable in the creative mainstream [1]. Poor guy probably had friends and family who didn't have any problems with his views.

You have the right to do so, but you also have the possibility of being nailed to the cross (apt metaphor, in this case) for doing so.
So taking the risk is stupid from a personal perspective.
A single district mandating critical race theory education won't by itself change a lot, but it's part of a broader shift in the zeitgeist's heresies. Does there need to be a shadowy cabal of progressives saying "yes, just as planned" for this to be true and noteworthy? The things you can't say today are different from the things you couldn't say 20 years ago. You don't need to breathlessly follow the news to know this, but you would be a fool to ignore it entirely. Regardless of whether you think these heresies are morally/politically good, every citizen needs to keep up to date on the latest heresies lest they run afoul of those heresies themselves.
Noting that slow shifts in the status quo are rare is rather unhelpful. Of course they're rare. But being familiar with the forest will help you find the right tree. The idea that the truth is a needle in the haystack is just as easily a prescription for consuming more news, not less.
That's not to say that you should. Perhaps your life is such that you've decided you don't need any of this or you don't need to find the true danger in every corner. Even dedicated experts find it hard to find true danger before it arrives knocking at the door. The value of finding true danger before it arrives is also debatable. Vast knowledge and the effort needed to acquire it is not an unalloyed good, it's a cost/benefit trade-off like everything else in life.
