PayPal's "acceptable use" policy excerpt:
"You may not use the PayPal service for activities that relate to transactions involving the promotion of #hate, violence, racial or other forms of #intolerance that is discriminatory."
The #SocialProgramming words are: "hate" & "intolerance" which are as ambiguous and fluidly definable as the one (in power, in this case, PayPal) can make it.
If it is #LEGAL PayPal should, by law, allow the transaction. That is how it used to be before the Neo-Bolsheviks/Neo-Maoists recruited/pressured Tech & Finacial institutions for its revolution.
