I have no idea what's going on, but would like to say to those who comment that they stay away from politics threads because they 'get nasty' that they are often robust, but on the whole people are up front with what they say to one another. Posters are only human, and tempers get frayed at times, but that tends to work 'both ways' and a group of people can be on one 'side' in some arguments but disagree on others.
I don't usually go on 'chat' or 'royal family' threads, but whilst you might expect them to be the least contentious, they seem to be where people fall out with one another the most.
