There is no actual community online.

Really? What's this then? A poster posts, another poster replies....and so on...
You seem to be drawing a comparison between comments on what we call a 'DISCUSSION BOARD' and comments made below a YouTube video!
Discussion boards are, by their very nature, a form of 'online community'.

Turnoi and Daffy and Foxy are composites of
postings that individuals can, and often do, weave into what they believe are actual
people. We engage in fantasy and narrative creation of all types to fill the void in our
actual lives. As adults we certainly have the right to do that. I would hope that adults
are aware that they are engaging in fantasy when they post online, but apparently many
believe in this sense of 'community'. If you are 'outraged' or 'hurt' by 'Trump
Diplomacy', you should consider how you view your online 'relationships'.

Not a question of being 'hurt', dear, it's more a question of wasting valuable time, thought and effort in replying to someone who we foolishly THOUGHT needed some help and advice!

Don't get the feelings of being 'hurt' and 'pissed-off' mixed up.
