Said that way, that's a bit misleading.
Ron did not actually threaten to throw down Vic, Ron only bragged on twitter that he was about to do so, big difference.
Of course, we all can safely assume that it was Ron being, yet again, all barks and no bite. It's easy for him to pretend on twitter that he was about to loose it, but I don't believe for a second that, if he was to face a potential physical confrontation, Ron would ever do anything but run away as fast as possible. I don't think Ron would ever "loose it" anywhere but in his imagination.
Ron only ever "fights" other people when he is hidden behind his phone screen.
Remember in his deposition, when, after he explained that he calls himself the sheepdog for he defends women and minorities, Ty asked him how he does that, and the only answer he managed to come up with was the single word "Tweets". This guy is such a joke...
