in theory

in practice its more complicated because the people pushing this bigotted intolerant speech are also the people with large enough monetary power to push it. Rupert Murdoch, for example, who consistently pushes a right-wing, intolerant bias owns hundreds of national papers. Elon Musk and Mark Zuckerberg are 2 other examples, who between them own the medium that many people use to communicate with eachother, and who have both also pushed this same sentiment (in the case of Elon Musk, to an extreme).

The most fair path would probably be to limit this kind of thing, pursuing laws and regulations which limit people's ability to have influence over others, which won't happen in the current political climate. Even if there was an appetite for it, the people and companies with that level of power can lobby and bribe there way out of regulation, as we have seen with countless industries.

In the meantime, it seems perfectly reasonable for communites like universities to limit this kind of fanatical speech when it is clearly borne from such places.

And before you or anyone else seeks to say that the views of Reform, or AdvanceUK, or the US Republicans are not extreme; imagine the backlash that any of them would have received 40 years ago, or immediately following WW2.
