I think you have opinions, on the other hand judgements need argumentation. You've simply stated that you object "to people who freely talk about negative experiences" because some other people you like a lot don't do that. That's not a judgement, it's just you expressing your personal preferences. It's not very interesting per se to be completely honest with you.
And the reason we have words is so that you can be told that you're confusing function with design/intent.
There is no intent nor design of a brain, they are a product of the evolutionary process.
