I think there's a kernel of truth there but also your take is bit broad and lacks some nuance. One can be contrarian and this allows to be open to heterodox views that most people would not even consider. There's no question that for many you are correct. But you could say the same for those that hold orthodox positions. They are just trusting the authority figures and have never looked at either subject with any evidence based approach.

What I have seen over the years is that people see one area where they had their mind changed. They feel that they were deceived and this breaks a trust they had in authority figures. This is a fork in the road. Some will begin questioning many things and start following any contrarian view without critical focus. Other will do the opposite. They will look at issues with a critical eye realizing everyone has an agenda and something to peddle.

What you are saying is bit of a straw man though it has a kernel of truth. There are weak minded people that just follow the crowd and ones that took one too many red pills.
