So you suddenly feel the need to "do something" about the fascism?
Step 1: Shut the fuck up. Don't get specific or even "vaguepost-y" / overly suggestive about your intention to do anything.
Step 2: Learn about security culture because you're more effective if you don't go to prison, and you need to not get caught before you do your thing.
An ordered reading list:
