Are there any communities where people have real intellectually honest discusions?

I know, I know, this is the internet and that's not how it works. However, I'm weary of attempting to have a serious discussion only to be met with unserious and intellectually dishonest replies. For example, asking a specific and nuanced question and only getting replies that ignore the details or the question entirely.

Are there any communities where people make an honest effort to have real discussions? Where we take each others points seriously, demonstrate we understand them, and then address them?

There must be some communities like this, right?

Edit: I need to clarify that I am not criticizing or complaining about THIS community! I'm looking for communities focused on specific topics that have this attitude.
