you only have to look at the make up of the parliamentary membership to relise why the laws on un-natural acts between the species have been ditched,
when Cameron decided he would include marriage between the same sexs, in the new parliament, and may I add without ever bringing it into the conservative party manifesto. his main man was at that time nursing his dying brother whom later died of aids, and the vote when called for was practically unanimous on all sides.
but ask your mp to back hanging for the most heinous of crimes and he would recoil in disgust
