Same sex marriage, for one, and you even noted that in your post.
It becomes a liberal trait when the person proposes to force their beliefs on you, or that you are forced to comply with their thinking. Conservatives support gay marriage as a freedom to choose or not choose outside of government force. A huge difference. Those who call themselves conservative when demanding government ban gay marriage aren't conservative; they are dictators.
We've had this conversation many times... I am against gay marriage on a personal level. I am against abortion on a personal level. But, I do not support the government banning those things simply because I am against it. I believe that's what distuigishes a true conservative from a conservative in name only.
