BA, if it's a mission to redress the political balance you want, why not pop over to the Socialist Worker Party forum?
Sure, it's a bigger challenge than MN, but with your wit, repartee and dazzling debating skills, along with your firm grasp of political processes and conventions, you'll slay 'em.
MN will only ever be reflective of its members' views- it's an internet forum. If more posters think David Cameron's a massive cunt than don't, then I'm afraid that will be the prevailing view of MN.
It may be time to put your superhero outfit away and just have a normal debate like everyone else instead of trying to 'redress the balance' all the time.
