It's so lovely for you being so sure that this will never touch your life. What if the fabled Chinese did invade this country and you were suspected of involvement in a plot to overthrow their new government? Stranger things have happened.
Also, torture doesn't work because people will say any old bobbins to make it stop.
And yes OP it is torture. If it was the guy I think you mean on question time he is an arrogant little prick with all the moral fibre of a packet of space raiders.
Are you in the business of protecting the UK. Probably not.
The very fact that you can say anything you like on this forum is because you live in a country which has an armed force. Yes armed and dangerous and probably torturers.
If you don't like it, then I would say have a great time when you land in one of those countries where you wouldn't be able to write doh without wondering if the thought police would knock on your door. Isn't Switzerland neutral. Perhaps you could live there.
After watching people burn the poppies today, my patience is running thin for people like you.
We should be bloody grateful that there are people out there that are able to torture someone (I certainly couldn't) to make sure you are safe.
I feel very sorry for some of the people who go into the protection of the Uk knowing there are people who feel like this.
