I have no wish to stifle alternative views - but I retain the right to consider some of them as rubbish. The idea of the future of Britain in the hands of the Greens or the Lib Dems fills me with dread - or at least it would if I thought there was even the slightest possibility of that happening.Why would you hope they lose their deposits? Do you want to stifle alternative views?
With the system that we have, their voices will never be heard to the degree that they should be...but it is NOT all about 'The Party', or shouldn't be. It's about what people stand for.
To me, the EU and our place in it (or relationship with it) is by far the most important issue of our times. Of course I will support the parties whose position on this issue I agree with.
