It sounds like you have been brainwashed on the term reactionary, and use it like a label to discredit those you don't like but don't have a valid argument against. That is why you are so desperate to not have Antifa labeled a reactionary when they clearly fit the description.

The most insane extremists seem to have the idea that they are in fact smarter than those who react to facts by acting before the facts. This is simply wrong. It means you are justifying your, usually evil, actions with predictions that are most likely wrong. It simply isn't true that you can make accurate predictions of the future. You are no better than a schizophrenic murdering people because a voice in their head told them to and as far as they can tell that must be God.
