Such behavior is not rare nor is it common. People on the Arbitration Committee see more than their share of it and it often results in the user being banned. Without being familiar with the article and its supporters ( I don't think you shared the name of the article ) I can't say if it is any regular editor with an account.
I hope you are not permanently put off by this incident, but learn to effectively resist the energy it represents.
