Unfettered free speech has never existed in this society, or any other recorded society as far as I am aware.
Terms of racial abuse, once not subject to mandate via criminal statute, now are. I think most people would see that erosion of what is ostensibly a freedom of expression as a good thing, so it’s not a straightforward issue. The law needs to evolve to reflect society and laws by their very nature impose restrictions on people. So just because freedom of expression is curtailed in some way, that isn’t necessarily a bad thing.
I think the ease at which people are offended these days, and the way that offence is permitted to be weaponised, is currently a far bigger threat to our civil liberties than any law that has been, or is likely to be passed by politicians.
The way that people can be rounded upon and hounded because of something they have said which others don’t like, with the end result often being professional and/or personal ruin is far a more pernicious attack on our civil liberties than any laws that have been passed in recent years, because the net result will inevitably be that people will feel less able to express themselves, not because the law necessarily forbids it, but because of the consequences that could flow from that from their fellow citizens.
The prevailing viewpoint through my life is that freedom of speech has been, in a way that is unqualified, a good thing - but that paradigm has been twisted because that same freedom of speech, exercised by those who have been offended, has come to be used as a tool to repress freedom of speech itself, so it’s actually now a lot more complicated because of that manifestation - allied to the omnipresence of the malign catalyst of social media, which brings out the very worst in so much of the population.
I’m not sure there’s any answer to this issue, either. Certainly not any straightforward one.
