Oregon gun shop REFUSES to sell firearm to Antifa-affiliated man

I''m not an FFL, I know we have some in the membership. Isn't one of the responsibilities of an FFL to determine the suitability of a customer. In refusing to sell, they open themselves to litigation, for sure, but in my mind, I think they have to determine, as the last line, whether or not the customer might be a danger to the community. Was purchasing the pistol online purely a matter of price? Or, was it a means of hopefully getting past the 4473 requirement???
