LOL.

The KKK was an actual organization. Antifa is a movement like feminism. Whether or not you like Antifa, or the fringe elements within the movement, is completely irrelevant to what it actually is.

Show me the leader of Antifa. Show me the president. Show me the equivalents of the Grand Wizards or Dragons or whatever having a dress up meeting where they discuss their strategy.

You can't, because none of that exists. It's just a counter culture movement that Republicans want to call an organization. Getting things called "organizations" is kind of a big deal. It's why Al Qaeda which wasn't really ever a thing was called an organization. It allowed the US government to bring its full weight down on it. Ironically, AQ only became a thing, after the US branded it a thing, and then it became cool for Jihadis to be like "allahu akbar I am in al qaeda".
