There are small steps that individuals are capable of and there are large steps which may be difficult to achieve. Each will work in a different way:
On the individual level, it reminds me of a story of a man getting pulled over by a cop for speeding. After speaking with the man, the cop let him off with a warning and told him he was not concerned about him as an individual speeding; he was concerned about the psychological effect it would have on the other 1,000 drivers who saw him speeding. One person going 10mph over the speed limit will initiate a chain reaction that may cause 100 over drivers to speed 10mph over the speed limit and 1 to drive 15mph over, even when they would have obeyed the speed limit had they not seen another individual exceed it.
The same effect can be seen with people who are wearing masks. If one person in the large grocery store pulls down their mask after entering and does so unafraid, unemotional, with quiet confidence or just with an excuse, like talking on a cell phone, 10-20 more will see him and decide to do the same.
If the store manager asks you to put on a mask, you calmly say "oops", put on your mask, then again stop wearing the mask when nobody is there to enforce it. When somebody with no official authority to enforce ordinances gets mad or makes a comment, you just shrug and walk on without saying a thing.
On the individual level, simple, small, largely passive steps are all that is needed: asking the questions you are told you can't or shouldn't ask (even if it is anonymously on in a forum like Q Anon) or simply getting very good at saying "no" when you disagree are surprisingly effective steps that tend to snowball across a population.
There is a reason communist regimes have traditionally made it a top priority to control the narrative, censor the truth, force compliance and rewrite history.
At a higher level there are several important steps that would be helpful:
Our equivalent of these "critical race theory" training programs would be "critical analysis and skeptical thinking" training programs, the goal of which is simple: get people in the habit of asking "What is the truth? Am I being lied to? How do I know?". If these could be implemented as common or required training programs in schools or companies, the effect would be tremendous.
The broad tech censorship needs to be called out and circumvented. The powers that be are tightly grasping at total control, but for every Rogan they buy and censor or 8chan they shut down, a new Discord or Twitch will pop up. The effect of the Q Anon movement has been huge, even though its original site was destroyed, because it could not be censored.
Judicial and legal freedom: If the legal system has the power to apply the law unevenly and selectively or as a cudgel to silence certain groups of people, compliance can be forced; It will be too risky to be a skeptic. We all remember the Lois Lerner IRS scandal, we have all seen the potential legal ramifications of facing an "accusation" (Kavanaugh comes to mind). The FBI has even justified attempted entrapment of individuals because they "were excessively concerned with individual freedoms." Freedom from irrational regulation and punitive political attack is a necessary precondition.
