Interesting, this resonated with me. I'm a "conservative" from the view of modern liberals (strictly speaking I'm a classical liberal or libertarian- I support gay marriage, the end of war, the end of drug wars, the elimination of income taxes, hard money, open borders freedom of speech and gun rights) ... and I will openly admit that the primary motivation for many of these beliefs is a feeling of a lack of safety.
I don't like humans being abused, physically or mentally, and I feel that happens way too much in our society, and all of those positions in one way or another are attempting to end abuse.
I know many liberals feel their positions are based on similarly wanting freedom (at least when I was a liberal that was my motivation)... which is why I think the great divide is largely due to wedge issues being shoved down our throats.
