Why are you so obsessed with who you think ought to be allowed on Free Republic?
Let's assume, for the sake of argument, that the above admission is a "liberal" position that one wouldn't expect here. I'd be willing to bet that it is the only position that poster has which might be considered un-conservative.
Yet, this site is full of people who supported W expanding the department of education with Ted Kennedy, it is full of people who supported W on the medicare bill, it is full of people who are just fine with illegal immigration.
I don't go around, on every thread, being "stunned" about why they are on FR.
There is a diverse group of "mostly" conservative thought on this board. You will be happier if you give up on insisting upon 100% ideological purity on this one issue.
Try posting an Alex Jones article on Freerepublic and then ask me that again.
However, Ron Paul can appear on the Alex Jone's show quite frequently and even propagate Cindy Sheehan/Rosie O'Donald conspiracies.
I can see the connection, but I expect some cheap magic trick, like, "look over there, he is for smaller government".
