Do you know what AV voting is?

I'm not sure how to vote about AV. To me it is the wrong election system if we are going to change, PR seems better and fairer. My instinct is for fairness in voting, but my fear is that with any other system of voting than the present one we will never get another Labour government with a majority.
When looking around other countries I see the party that the majority have voted for hampered by minor parties who are brought in to make majorities in their parliaments and so have an undemocratic influence, such as regional parties in Germany or the extremist religious parties in Israel. I would like to see real socialist parties at Westminster, but not the BNP or more Nationalists having an undue influence due to the need to get over the 50% mark, and that would happen. Democracy doesn't preclude the idiots and the evil that is its problem!
AV is not a good system. It works well as an internal electoral system, for instance choosing committee chairs or even party leaders. PR would take away a lot of the close relationship we have with an MP, we'd be voting for party not the person, which maybe many of us do anyway.
I find it hard to support anything that Cameron puts his name to and equally hard anything Clegg supports, so I may just spoil my vote! But I do fear that if the No's win then that will be the end for a generation of electoral reform discussion.
I feel an issue of more concern is the cutting of the numbers of MP's and the redrawing of electoral boundaries, this could really change things and I feel for the worse (as it has done in Stoke-on-Trent for the Council).
