Speaking about countries and differences. Here where I live, we do have Pride marches once per year. The first one, which was kind of "march" was a real disaster. So after the lessons had been learned, all the subsequent Pride marches took place as insider event in the park, located in the centre of the capital. Why? Because that park has a metal fence all around of it, there is HUGE presence of police officers, including fully-equiped riot police and participants and general public are kept apart by barriers. So, if they would suggest me taking 24/7/365 RLE and I would not be passable at that point of the time, then this all would be pretty much screwed and I certainly would have been taking a case before the ECHR.
I do not want to insult neither the NHS, nor the UK system as such - if that works, then at least people can get what they need (though my personal opinion is that I would never move to the UK, because laws are crazy there - flat firearms ban and You cant even own pepper spray for self-defence...).
