I think what is interesting is that we keep needing these pages to teach people how not being an asshole works. I don't really understand why it is so hard to understand not to do (what I consider to be) impolite stupid shit.
Tip 1: Starting off by denigrating folks who do this is not a way to make people change. More often than not, it amplifies the behavior you don't like.
Tip 2: It helps to indicate you understand the perspective of why people do it before asking others to change. Reading your comment, I really doubt you understand their perspective.
People listen to those willing to understand them.
I do not. That is rather the point of the original message xD
My problem is having to explain this stuff to adults in the first place. Somewhere in your first 12 years of live you should have learned not to do things like this (e.g. most people figure it out in elementary school)
Even a real person calling me on my phone to talk 5min about its company without allowing me to interrupt feels like a kind of grenade. Obviously I could interrupt the impolite way but that's beside the point.
