I don't know about Badnarik, but I know that Paul doesn't support the homosexual agenda.
Let me emphasize I'm not trying to get libertarians banned.
Why would Libertarians get banned?
Their philosophy is nearly identical to that of the GOP with the exception of the WOT and the WOD. I know that some Libertarians support abortion but there is an off-shoot of the LP (much like the GOP has the Republican Liberty Caucus) that's pro-life.
Because comparing it with Mr. Robinson’s original post, there would be reasonable particulars for banning supporters of Ron Paul and libertarians in general.
