That's one take.
Another is that it's the latest in a long line of historical trends which showcase the intolerant human impulse to eliminate perspectives that one despises (e.g. the stoning of Jesus, the Crusades, the Salem witch trials, tar and feathering, Communist gulags, Nazi book burnings, pulling down statues).
What might be regarded by some as "the mainstream is thankfully no longer putting up with" could alternatively be "the mainstream would rather be intimidated into conformity than risk being vilified and harassed by the mob". As it is with individuals, so too with organisations, corporations and public figures like politicians and celebrities.
So I agree the status quo is certainly being changed, but it appears to be by coercion, rather than through reason and logic. As such, I wonder how much of the change would stick if the coercive element is removed, and whether the sustained coercion is giving rise to negative long-term effects such as resentment in those being coerced and threatened.
Anyway, such is the wonder of different perspectives being freely and respectfully shared, and why discussion forums are a superior format to re-education facilities IMHO. Assuming we follow the site's Terms of Service, we get to hear and share opinions, and make up our own minds, informed by a cross-section of views and sources of information.
All the best.
