I was not a Republican because it seemed to me that the right always tried to force their vision of God down my throat with things like school prayer. I was NOT a Libertarian because I simply DO NOT trust big business to police itself. My grandparents lived thru times where big business was ruthless and cruel to their employees. The Republicans were also known for that but not as bad as the Libertarians. So that's how I became a Democrat. BUT now I feel that the Democratic Party is more communist/socialist than I can stand. I also hate the lies and out right dishonestly that seems to be epidemic in the Democratic party since Bill Clinton ... who I happen to despise BTW.
My grandmother went to work in the silk mills of Paterson, NJ at age 12. I know what you mean about big business and a need for unions. I myself came to hate unions in a big way by observing first hand how they operated when I was a carpenter in my youth not to menition their historic ties to communist organizations and organized crime. Speaking of the history of labor, Government and crooked pols enabled much of the buisness abuse of the working force and retarded reforms. Sending in the National Guard and all that.
On to your point about which party to join. If you believe in God, then you believe that man is corrupted by sin and therefore we will never perfect society totally here on earth however freedom is still the best route to go. Remember government is force. It says you can do this or can't do that and to get you to comply will either fine you, jail you or kill you. And the more government controls societal activities the more reason people have to bribe politcians to get their way. More government breeds more corruption. Limited government is the only cure for that. To those in charge now it is not in their self interest to reduce government influence. Maybe tinker around the edges just to fool some suckers into voting for them but that's about it.
