which goes well with your general disdain for organized labor. What you have not answered though is why this particular type of freedom of association should be banned when others are not.
I think the IRS, and the general expansion of the administrative state, offer literally hundreds of thousands of reasons why.
Please clarify how that is in line with the statement it was posted in reply to. Other than you hate both organized labor and the IRS, I don't see a connection between the two.
If someone choses of their own free will to be part of a union how is that different from choosing of their own free will to be a member of a specific church?
Crazy thing is, we don't have churches making decisions about how to regulate the lives of random people.
And neither do unions. Unions work for their members. How do you see unions being somehow magically able to "regulate the lives of random people"? Union members pay dues and vote. Arguably unions - which few remain of any relevance, anyways - are a more direct form of democracy than what our country has devolved into (even more quickly so since the passing of Citizens United).
