Human nature Dave.
As I have mentioned previouisly, people feel passionate about their own individual issues, either by personal experience, or simply because it is something about which they hold strong opinions.
I do endevour to put forward my views in a detached way, in matters such as sexuality, which is a frequently and hotly debated issue here on AB, that is not a problem, as i have no personal issues to raise or defend.
I agree that an element of debate rather than personal insults is required, and largely met, but as in life, some people get a little bit carried away.
