so this cuts both ways. You voluntarily publish your "beliefs" widely and publicly, be prepared to be called on it. Most of us choose not to do this, but if you want to exert influence you are held inviting criticism.
There's nothing wrong in being wrong. I'm often wrong, and I'm very happy when I learn something and cease to be wrong about that.
If you take the political views angle, up to 2005 or so, I was very much for small State and liberal economics, but, over the years, I observed the results of assistance programs for vulnerable populations, industrial policies that developed entire regions, and other measures that ensured more opportunities for upwards social mobility, especially for populations that were often excluded from that. Then, in 2015, a coup came, that ousted a left-wing president and demolished most of those policies. Then a far-right president finished demolishing what was left.
At this point, I am very left-leaning because of this. I have seen what injustices do, and how we can eliminate them - and it's not even hard to do so. If even a relatively poor country such as Brazil can do that, anyone can.
That is highly dependent on what you're wrong about, and if you change your beliefs based on evidence, and how many people you try to influence to believe your wrong beliefs.
It simply flagged that he was on the “wrong team”.
