Look, I'm all for freedom of speech. I just happen to think free speech absolutism can be either two things; hypocritical, or completely off the rails gullible conspiracy theorist.

1. Hypocritical, if you use any of the following: Twitter block lists, adblockers, e-mail spam filters or public blacklists. (Just to mention a few things.) It is not absolute freedom of speech, if you agree to using these kinds of suppression.
2. On the flipside of the coin, you'll be subjecting yourself to all sorts of quackery, scams, conspiracy theories and penis enlargement ads.
   If you believe in voluntary brainwash "on the gullible" by the mainstream media, try applying the same logic to your incoming e-mails (normally in the spam folder).
   Consequentially you'll be subjecting yourself to all sorts of security breaches.

If you don't censor any data from the information you consume, you'll be effectively teaching your brain to accept all kinds of lies as "information". And in the worst case scenario, you'll open yourself up to actual exploitation.

You may claim that you want to "be in control" of who and what you personally believe online. Good luck spending your life doing that instead of actually living it.
