This is becoming very political very fast, so I expect this thread will soon be locked.
The problem with trying to silence "hate speech" by "canceling" any organization that does not block it to the satisfaction of political activists of all persuasions is that it leads to "information silos" where proponents of competing philosophies get separated into like-minded groups that do not communicate with each other. This provides a fertile ground for inciting both sides, and seems to lead to actual dangers of physical confrontation, terrorism, etc.
Even the definition of "hate speech" gets weaponized in different ways by different groups. And, if the government gets to define it, that slippery slope leads to abuses like what we are currently seeing in Russia, where calling the military conflict in Ukraine a "war" or "invasion" gets you multiple years in prison. Similarly, saying anything critical of some religions can get you executed in several countries.
So, in the U.S., we have a philosophy that people should not be constrained by the government from speaking their minds - that is enshrined in the First Amendment to our Constitution. With the government out of the censorship picture, here, political activists have realized that control of the "news" media and religious organizations provided them the way to indoctrinate the masses into their various philosophies. So, we see this effort to cancel just about anything that somebody disagrees with.
Frankly, I have never seen any racial, ethnic or religious group of human beings that is beyond reproach and worthy of protection from any criticism. And I have seen a lot of criticisms of bad behaviors get labeled as "hate speech". That is intended to, and does, prevent rational discussions over issues where 2 groups have legitimate conflicting interests. Without discussions to reach consensual compromises, polarization increases and physical conflicts ensue.
So, my recommendation is that we need to openly argue against what we believe is wrong, rather than try to block every statement that we think is wrong, or maybe even true, but not helpful for our own agendas. Forums like Twitter can provide for that, and are really no worse for society than forums that allow only one point of view.
And Twitter can still be used for non-political science communication purposes without engaging in the politics. So, this effort to stop science communication on Twitter is really nothing more than a political effort to "cancel" just a few of the groups now allowed on Twitter at the expense of cancelling all of Twitter. What is the alternative? It is to have groups that allow scientific discussions be limited to only those that censor information. I don't agree that is a healthy condition for "science" either.
