In a word, no.
Free Republic permits the free exchange of ideas, and even the trolls and moles are good for verbal target practice. Besides, it is fun to peel their 'arguments' apart.
Otherwise, we end up preaching to the choir.
Without sparing partners, the arguments get old and stale. Over time you turn into putty.
I say, let em in, bring em on!
FreeRepublic, where the slow and liberal are shaken, stirred and eaten! BWAHAHAHAHA
plus.. we wouldn't have use for the kitties anymore!
