Officially, the JBS is anti-Hitler and anti-facist, but the membership of that org. tend to have those sympathies. I have known several Birchers in my day, and they were to a person anti-Semite and racist. What idealogy does that sound like?
If they were, they have probably been discovered and kicked out by now. Any form of racism is not tolerated in the JBS, and prospective members are screened before their membership application is accepted.
