"Why should I (as a tx payer) contribute 14% to a pension for someone else, who only contributes 6%. I would love all the public sector workers to contribute to my pension, but can't see that happening."
But actually, isn't it true that very many private sector workers don't contribute to any pension at all, and that with this redistribution, public sector workers' tax is just as likely to be paying the pensions of these workers as your pay is likely to pay theirs? Why does your pay contribute to their pensions, when they are all paying tax too? 
I don't have a problem with pensions being radically overhauled, actually.. but I think it is unfair to ask people who have worked in particular positions for years, perhaps sometimes staying in that job purely because pensions were an incentive, who have this ripped off them, say, 5-10 years before retirement. There are many more fair and transparent ways of approaching this problem.
Some jobs require more energy than others. I, for one, don't want to see e.g. young children being taught or fires being fought by people hitting 70 who are working unwillingly because of fear of poverty. Dh is an engineer and works with some people who come in after retirement to do some extra hours, and they make a fantastic contribution (one man nearly 67) but it is voluntary and they are doing it because they love and have passion for the job, not because they are desperate. They can also sit down all day! I don't see how forcing rather than encouraging people to work well into their late 60's and approaching 70 will work in some public sector jobs, and I think it could be dangerous.
I have only been working 6 years, I haven't paid much in, I have time to make alternative arrangements. Taking it away from people who don't have this opportunity, who are due to retire in the next ten years, seems very very wrong and I think it was wrong this was done in private sector roles.
That's what I don't understand. As Lord Hutton put it, the race shouldn't be to the bottom. Reducing pensions, in general, won't benefit any private sector workers. The expectation will be that the annual worth of a pension (which in private and public pensions averages only about 8.5K at present) will go down across the board and more elderly people will have to work long beyond their health sell-by date in some cases whike finding themselves increasingly impoverished. How is that in anyone's interest, public/private sector animosity aside?
