Self censorship is something I have always failed at.
Caused me many problems in school, I could never keep my head down and be silent whenever a teacher was spreading misinformation.
I got suspended for arguing with a teacher because they told the class that Australian does not have a constitution and called me stupid, said that only USA has a constitution.
There were others just as smart or aware is a better word as me, who were able to practice self censorship, and they have had much more "successful" lives than I have, because when their employer says something they don't like they just carry on, while I tell them to get fucked and explain why they are wrong.
