What I find interesting is quite how un-political most of the debates are. There's strong arguments both for and against from people at both ends of the political spectrum and everywhere in between. I find it great to be able to openly discuss the pros and cons without having to worry about offending anyone's political sensibilities.
The people who are coming off worse IMHO are those who seem to think the answer is obvious and doesn't warrant any discussion (i.e. most of the political establishment)
