Because Free Republic is a forum. Members are free to post whatever they want, and those that are interested will add content. Members are also free to not read threads that don't interest them, and go elsewhere.
Sorry you don't see the distinction.
I might add (to bypass a smokescreen) that members are free to post whatever they want, within the confines of Free Republic’s restrictions and its moderators’ judgements.
Other than that, there’s nothing wrong with this thread.
It’s not a liberal forum.
