> Nobody thinks this way about actual strong convictions they held like belief in god or abortion or polygamy.

There's no need to change that kind of strong convictions, what needs to change is the desire to use such convictions as justification for policies imposed onto others.

> Even the same academics that would change their mind quickly about some theory would never actually change their mind on their strong ideological convictions

Again, that wouldn't be a problem if they recognized the right of others to think differently. Their propensity to invoke "science" to justify intrusive policies, one way or the other, is the real problem.

> So I repeat again if you changed your mind under influence of an internet stranger then it wasn’t a very strong conviction.

To paraphrase Keynes here, those who don't change their minds when facts change are simply fools or trolls. And the realization of change may come from a single word, of people known or unknown, or even without words - it doesn't matter, change must take place when change is due.

We could argue about the semantics of "very strong convictions" until the cows come home, but it won't do any good if we haven't beforehand agreed upon "why we argue".
