On a ride today mind wandering a bit and thinking if I had the opprotunity to sit down 1 to 1 with Trump to discuss "anything" what would I say? And realised I wouldn't say anything but I'd just walk out as I have far better things to do with my time that explain fact, science, reality, etc. to somebody who is totally unthinking and whose response at best would just be rude and insulting. And even if he listened and absorbed ideas, 10 mins later he'd have completely forgotten them.
Such an opportunity would be a complete waste of time when there are so many interesting useful things to be getting on with.
Same applies to trolls.
