Right.  The original headline was false.  Wrong.  No whites only group.  

Gavin is not a white supremacist, a white nationalist, nor belongs to a whites only group.

Bloggers, journalists, reporters and others who publish that he is are publishing something empirically false.

For that he has to pay a lawyer to get the lies taken down.  Unfortunately some bloggers, journalists and reporters fail to fact check their claims.  

The other claims I don't think Gavin worries about.  Or else he just publishes a retort that explains why they are wrong.

The initiation into Proud Boys is more silly than violent.  It is hilarious that the New York Times published about it.  Again - very simple fact checking shows what happens at the initiation.  Not quite as scary as the journalist at the Times pretends it to be.

The initiation is silly and light-hearted.  Not really violent.  They are just men being men.  He is not going to sue them for their characterization of it.  Why would he?
