Conservatives do not endorse any government action to defend morality and the traditional family structure simply because we believe it isn't governments place to decide morality for us.
Does this reflect the reality of what's happening in the U.S.? Isn't it really the conservatives who are initiating actions that would cause their morals to become law? I'm thinking of the many constitutional ammendments that ban same-gender marriage, and anti-choice activists who want to make abortion illegal. Aren't those initiatives instigated by conservatives? And therefore, don't conservatives think it is government's place to decide morality issues?
