I have wondered this question too : p I dont consider myself a liberal, or anything. I mean I do in some ways, kinda?
I dont agree with some of the social issues they focus on currently. I agree, all people of every race and sex and nationality and all that should have equal rights. But the focus on personal life choices, and throwing that in there, I think its meaningless, and is leading many many young people away from God.
I agree with social programs that aid the poor. And I agree with them known people who do purposely keep their income level low enough to receive it in order to work less. But I also know someone who has worked hard her whole life, has a college degree, worked a full time job, raised four children on her own, and is now hurt and needs assistance in order to live, and cant take care of herself. I agree with rules to help prevent people from misusing the system, but not when it gets in the way of people who do need help.
I think it depends on what you mean by "liberal". I avoid the path of the world. I dont believe that nonstop smiles and never saying anything that people dont wanna hear will bring peace on earth, I think it will actually open the way for evil to take advantage of it. I think it is right to practice self restraint as a society and turn from lewd and evil things. I dont believe that sexual freedom is in /any way/ an important issue that needs to be worked on. I believe in freedom, and equality, and loving everyone. But I also believe 100% that Gods way is the best way. And instead of trying to fit my political beliefs with God, I make God the deciding factor of my political beliefs.
Dunno if that helps you, its just what I have come to at this point : p
