I'm wondering if a fascist database could be useful?

By this, I mean gathering all the vile crap and bigotry these people say, whether a tweet or a politician quoted by a media outlet. If we admit these fascists may commit massacres on a mass scale, including within the West, I think it would be wise to gather and archive all the evidence for a future Nuremberg trial? I know many of us want them to get the death penalty without a trial, but I was thinking social-democrats/liberals should be in this database too because they should be held accountable for their bigotry. Or am I thinking too much and this is stupid?
