I'd say empathy is a social skill learned through experience or proper education.
It can still be distorted and applied selectively or even outright ignored.
And at its core, it can be both simple and complex. Whatever emotions you feel and why can be felt by anyone else in the same way, but perhaps for different things.
So the main thing empathy asks is to understand that, to accept that having their experience and knowledge from their life is what guides their decisions, just as your own guide yours.
We don't know the same things and we should appreciate that difference, even though we might not agree with it.

What's interesting is that the language allows multiple meanings. The commenter above can either be driven bonkers by presence of nuance or the lack of it and both interpretations are correct.

The first sentence can be seen as being against nuance or it can be seen as being against the online experience of asking for nuance.
The next sentences can be seen as arguments against nuance or examples of behaviour encountered when asking for it.
And the final bonkers can either be against the use of nuance or the repeated responses to it use.

So without further clarification, we can't really be sure which stance the commenter implies.
With only these two situations presented, it's a 50/50, left or right choice, so I'll go ahead and presume it's the latter, since that seems to be more likely encountered in online chats.

The key is having someone or something you're satisfied with and keep at it for the joy they provide.

WebMD says it's a brain tumor. Or an ear infection. Or lupus. But it's almost never lupus.

Empathy is generally described as the ability to take on another's perspective, to understand, feel and possibly share and respond to their experience.

We're all the same, equally susceptible to bad influences that can compound and overwhelm our sense of right and wrong.
No one is beyond saving, but sometimes the effort needed to do so is impossible to reach.

So if some random hacker takes over your network connection and publishes illegal content which then leads back to you, you should be held responsible. It's your platform after all.
