Read a newspaper for information.
Don't read it for salvation, or to show allegiance. If you restrict your exposure to news to only those outlets you deem morally worthy, then you risk sealing yourself in a bubble.
Capitalism is doing odd things to people's moral compasses. So many people seem to make moral judgements on very slight bases.
So we get 'dog whistles' and cancelling, ex-communicating those who've sinned. There seems to be a real fear of contamination when it comes to thoughts and beliefs. A new kind of pseudo religious thinking. Tribal, simplistic, and superstitious.
I guess if you don't practise critical thinking and interrogate assertions, seek evidence, look for altnerative views, then you may indeed be more susceptible to being accidentally brainwashed.
