I identify with the left, but this mindset is holding us back. I don't understand why the left feel that they have to use underhand tactics when discussing their ideas. It goes to a base level, where the Tories are 'evil'. I just don't get it, clearly Cameron doesn't just hate everyone, he just has, in my opinion, incorrect theories about how to improve the state of our country. So if we are to debate it, then we must know the facts and structure a debate!
At Uni, there is a fair bit of hate towards feminists. I didn't understand at first, but now I realise that whilst I completely agree with their points most of the time, its the way they go about their points which drives everyone mad. Debate the ethics of abortion, don't lobby for a pro-life activist's speech to be cancelled. It drives people to his side. Hear him out, and then if you are so sure you are correct on the matter (and I am), prove his logic incorrect afterwards.
