The Coronation.

Because you display a fundamental misunderstanding of Parliamentary Democracy. I, and others, have explained this to you more than once, but you just don't get it, either because you really don't or are arguing for the sake of it. I hope it's the latter

I never said you are all dumb, but you fail (it appears) to understand the difference between arguing a point outside of Parliament and one within it. The one within it will/could result in a valid law on the statute Book. The referendum was never that, it was a proposition put forward by a group of people and the government of the day decided to put that to a public vote. It was NOT LAW at that point. That law had to be drafted in Parliament in the form of agreeing the final Treaty. However given the narrow majority it was perfectly legitimate for MPs to represent the views of the 48% who voted remain. Whichever party they were members of. All this was only legitimised at the end of 2019 when Johnson won his mandate and we signed the leaving treaty.
The current laws on protest are equally legitimate laws duly passed in Parliament, nobody is suggesting otherwise.
However, as UK citizens we have (or had) a right to protest, argue for amendments etc. Any law passed in Parliament is subject to review and amendment, by Parliament, as they have been through the ages. Nothing is set in stone.

Now some MPs, some in the Police force (it now seems) argue now that recently passed protest laws are overbearing and poorly drafted. I find that (personally) comically ironic because the people (party) that drafted them and passed them through Parliament (over ruling the House of Lords at the same time) are fundamentally the same people who led the leave campaign and drafted/passed the departure Treaty with the EU.
That also being a pigs breakfast, detrimental to economic well being of the UK and detrimental to the freedom's of our younger generations, ones' us oldies enjoyed for decades.

So Parliament is sovereign and we all (apart from a tiny minority of loonies) respect that. But Parliamentary Democracy demands participation of the people it represents (or it dies) and that participation takes many forms beyond ticking a box on polling day. Hence debate and protest.

However, if you vote for manifestly stupid and indeed malevolent people then you tend to get stupid and malevolent policies and laws. That is the wonderful imperfection of Parliamentary Democracy.

I would argue that this is exactly why we have the disaster resulting from Brexit and exactly why we have an increasingly authoritarian government who seek to suppress dissent as evidence of the poor outcomes of their policies since 2010 has come to light.

Hopefully at the next round of our democratic elections they will be soundly defeated and we can undo some, if not all, of this stupidity.
