Why are there so many fake Libertarians invading social media platforms?

So many times I’ve read posts on Facebook, Twitter, and even Reason comment section by these snowflake fake libertarians.

Its always like this:

Libertarian organization expresses a viewpoint.

Fake Libertarians: “OK I’m done! I can’t vote for you because of this viewpoint!”

Runs back to other two parties and accepts every lie, doublespeak, and fake promise.

They make up controversies, use gymnastic logic, and are just angry. Why? Why are they even here? Do they hate the idea of more voices that much? So annoying.
