It's best to judge people by their actions more than their words, but on social media, you only see people's words.
I know this sounds pretentious (which is quite ironic), but this is something I've noticed about the internet. You never read about what someone does, only what they say. You hear politicians claim that they'll fix the economy, or celebrities make speeches about what they feel like, or what "message" a fictional movie has being discussed over and over, but none of that matters, because it's all saying and no doing!
Although I'm curious to know if it's a full or multiple round action. With traditional D&D having 6 seconds to a round, it might be two rounds, maaaaaybe three.
Showing up to a protest is also an action. So is smashing someone's car. Do you think you can feed the hungry purely by posting thoughts on social media?
Translation: "I have no way of arguing with this obvious and simply stated fact, so I'll pretend they're 14 and think it's deep and then attack them for that. I'm 28 and this is a worthwhile use of my time."
If you have actions and words, then you should judge them based on actions because that is what they did and not what they said. The actions are more important than the words. If they promote peace and love, but spend their evenings violently attacking children, then their actions speak louder than words.
If all you have is words, then you work with what you have. At that point you are responding more to the message they are expressing, not necessarily to them as an individual.
Words are one type of action - like if someone refuses to say something, that's a choice right there. e.g., I'll say it: "Nazis murdering people is bad", but there are some who won't say those words... and that's really saying something (managing to convey a message of a whole other sort).
Words are cheaper than most other types of actions though. Yet also they can amass in bulk, and there are ways to follow through e.g. if someone says they fixed something in a piece of code, and provide a GitHub link, you can verify that the words match the deeds.
Edit: also I find it hilariously ironic to see these early downvotes, essentially judging these words without even offering an explanation, so perhaps we should say that while actions are more weighty than words, votes (up and down) are the cheapest of all 😂.
And 'Nazis' too for that matter, I don't know if you mean literally members of Hitler's National 'Socialist' party, or something else.
I would generally concur that killing (murder is sometimes defined as 'unjustified' killing, which is screaming for a definition of what is 'justified' killing) does more harm than good, ie is subjectively immoral according to my own sense of morality, which was shaped through my genes that were shaped by evolution, the society I live and grew up in and the experiences I've had.
But killing in self defense might be moral. If someone was a member of the Nazi party because they lived in 1930s Deutschland and didn't feel like they had any other option if they wanted their family to be safe, but didn't actively participate in it or help oppress minorities, and found themselves stopped on the way home by a person with a gun one night, who threatened to kill them, would it be that immoral for them to shoot their attacker in self defense?
Of course, you may disagree with me on various aspects, that's why it's important to clarify your terms, and not make blanket and loaded statements such as 'Nazis murdering people is bad'.
Edit: for the sake of clarity, everything after the first line is an edit.
From your question, I can infer that you - even if only for the sake of argument - are taking the position that it is subjective? In which case, feel free to do so - but don't be surprised if not everyone picks the same definition.
There is definitely room for nuance, but I tried to pick an example that was fairly clear & unambiguous according to most people's understanding of that term.
For sure, and with even a teensy bit of reflection I think most people would agree that people are generally quite shit at expressing themselves with words. We say things we don’t mean or imply things we didn’t intend to all the time. A well written book or article takes hundreds of hours of re-writing and getting feedback and re-writing again just to try to communicate the author’s idea effectively. Snap judgments based on social media posts alone are pretty baseless.
