The UK government are set on eroding any right to protest that is left. Please do anything you can. I don’t care what banner you do it under, just please do something.
Michel Forst, the UN Special Rapporteur on Environmental Defenders, has scalded the government for their draconian crackdown on any people trying to sound the alarm but as we’ve seen recently, there is no justice system and countries cannot and will not hold each-other to account.

I think at this point you might have been treated as hostile for the perceived tone in which you started your questioning. Though healthy skepticism is a good thing, you might have gone about it in a different way and got better results.
As an outside observer I would say that your hostility was met with hostility. You often get what you give, which is a good reason to be critical of your own writing. You can do better next time, please try.
