its funny you say that, because the right consistently tries to take away freedoms. the right is trying to legislate the right for same sex couples to get married, they are trying to legislate away the right to not believe in religion by forcing prayer in school, legislate a woman's right to have an abortion, legislate that women who want to have an abortion go through personally violating procedures prior to doing so. you feel the need to legislate the rules between an employer and a union. you may say you believe in a small and unobtrusive government, but in practice you support big government intervention when it suits your personal beliefs and needs.
You do realize that the so called gay marriage movement isnt about giving rights, don't you? It's about empowering the government to regulate homosexual relationships. No one can stop homosexuals from entering any sort of private agreement they want to and calling it wahtever they want. But the government can't have that. They have to be in control and regulate everything. I would have no problem if Government didn't regulate regulate marriage.
And no. Telling people they aren't forced in an organization doesn't regulate rules betweeen an employer and a union. Preventing unions from seizing "dues" from people who want nothing to do with them and spending them in ways they dont want, is not regulating the relationship between an employer and a union. It's empowering individuals to make their own choices.
Which is of course, why the left doesn't like that.
