Sorry but you don't seem to understand how Mp's operate.
It's like the same old chestnut about capital punishment you can have 90% of the population in favour but if your mp does not agree he will not vote for it-that's how it all works,you can jump up and down and do all you want but he won't change his mind.
now I could vote for another party who's mp's might carry out my wishes but they probably would not get elected as the main parties have and possibly will always have power and these parties are too scared to sort this crap out.
