Speaking with others is an opportunity to learn something, don't you think?

Yes 🙂

And one of the reasons why I don't block anyone.

You never know what you are going to learn from even people that you greatly disagree with.

Almost always, but I have a caveat (and I'm all about expression), some things you learn in life can not be unlearned.

Opportunity to speak, but not sure about the learning part.

Definitely! Don’t wall yourself off.

Opportunity I suppose

absolutely!
