//Being inconvenienced is not the same thing as having freedoms curtailed.//
It depends on your definitions. Being able to go about your lawful business is as much a right (and I would say more so) than being able to protest when it "inconveniences" others. Some of the so-called protests that have occurred in the last couple of years have been nothing short of concerted attempts to shut down parts of large cities. What you're suggesting is that protesters should be allowed to continue their activities unmolested by State interference, whereas those who have no particular views on the subject of the protest must suffer the "inconvenience" that such a protest brings.
//I'm afraid if you believe that then you have very little idea of what actual oppression looks like...//
I haven't read the full proposals for the Bill but as far as I can see from a cursory glance, as far as protests go, it simply aims to align the provisions currently in place to control mobile protests to be extended to static protests.
That may well be true. But then nor, I imagine, do most of the people who obstructed Oxford Circus in 2019. Preventing people from fabricating severe inconvenience is not, in my view, oppression. If it is, then I can only say "bring it on." The idea that groups of people with a particular point of view on a topic can seriously inconvenience others who have no particular interest in it is, to say the least, somewhat arrogant. e.g. "My protest is far more important that you being able to get to work/hospital/doctors/shops/whatever, so you'll just have to put up with it."
