First, it isn’t an ‘alliance’ with the 9/11 Truthers, he is the self proclaimed father of the 9/11 Truth movement and is responsible for much of the crap you read and there is very little difference between his statements and Rosie O’Donnel’s statements on the subject.
Next is his associations and promotion of racists and antisemites like David Duke and the late Ted Pike, of whom he hosts some of articles and had on his show.
Next is his continual pushing of conspiracy theories such as FEMA concentration camps, etc, that are more at home in places such as Renese or reruns of the X-Files.
With that said, this is just the tip of the iceberg. The first two reasons alone make him and others like him not welcome here. Our side is about Conservative values, not antisemetic fear mongering.
Thanks for your reply.
