This isn't your college or work place break room. If people are saying something you disagree with you can just say it and you won't be fired or ostracized for it. Yeah, people will probably get angry and say mean things to you but those are just words which can be ignored. Offence is taken, not given.
This is mostly for the lurkers who upvote unpopular opinions but don't comment. You can speak up - you're not alone.
Never say anything you aren't willing to stand behind. Because it won't go away. And with authoritarian regimes coming to power... you gotta be cognizant of the potential consequences
But generally, I agree with you. The further we get away from groupthink the better we are for it. When we self-censor out of fear of disapproval we are perpetuating the cycle and making it more likely the next person doesn't speak their mind.
Just because everyone believes something is right, does not mean it is. The majority has been wrong in the past and it will be wrong in the future.
