I would suggest you don't really know many conservatives and the conservatives you do know probably aren't really conservatives.  My father-in-law is as conservative as they get and a retired research chemist who bring AZT to the market.  He believes in global climate change so much he doesn't stop talking about it and drives everyone nuts.  Many would call me a conservative (and worse) but I'm not and I believe global climate change is real, gays can marry each other all they want, trickle down economics may work if properly applied with a lot of other economic reforms.
