Liberals are the ones that want to impose their standards on everyone. The Conservatives are the party of live and let live. They may disagree with many of the choices people make these days but they know that giving the government the power to impose the 'right' choice on them is dangerous in the long run.
It is Liberals who want to regulate what you do in your bedroom, what you put in your body, the words you speak and the ideas you have in your head. So tell me again, kids, why are they the 'cool' party? Maybe the Conservatives do represent a bunch of people wearing cheap suits blocking traffic on Sundays going to Church, but they are not trying to make you go to Church. The Liberals are forcing you to go and, baring that, bringing the Church to you.
