Learned just now that there's a name for arguments like "If you deny you're a racist, that proves you're a racist." It's called the Kafka Trap. https://www.jesusandmo.net/comic/guilt/
Eric Raymond coined the term. https://antifeministpraxis.files.wordpress.com/2017/06/kafka-trapping.pdf
Liberdon is a Mastodon instance for libertarians, ancaps, anarchists, voluntaryists, agorists, etc to sound off without fear of reprisal from jack or zuck. It was created in the wake of the Great Twitter Cullings of 2018, when a number of prominent libertarian accounts were suspended or banned.
