"Many of my Brit friends really struggle with the "freedom of speech" thing. They profess to understand it and the superficially do but they can't really grasp the full significance of it.". What do you mean "the full significance"? It's not just the US where freedom of speech underpins all, democracy depends on it, wherever that form of government is practised, and the effects of the failure to enjoy such can be seen in Russia, China, North Korea, Iran etc etc.
What I find puzzling is that intelligent folks like yourself and some others who post here persist in believing that Trump and his acolytes believe in free speech. Were he to be elected, God forbid, his threat to be a Presidential dictator will become true, and your beloved freedom of speech will exist only for those who agree with him. The strength of a democracy isn't gauged by how much self serving agreement there might be, but how it copes with opposition and challenge. Trump hates challenge and opposition, his temperament and behaviour has shown that on every occasion where his views and actions have been challenged, the spots won't change were we to be faced with the horrific prospect of him as President.
BTW, just going back to the post by OW? Any real fact checking going on there?
One example from the list of supposed media snowstorms that caught my eye "The same media that tell us the US economy is just fine (with 20% inflation)."
So all these organisations, most of whom make their living from providing accurate, factual, peer-reviewed information regarding the economy in general and in this case inflation specifically, they're all conspiring with each other to provide false information?

Criticise the media by all means, the get stuff wrong all the time, but at the very least do some homework before the "facts" that are given get held up to be as real as the eating cats and dogs story was.
