That wasn't my intention. It's not "woman dramatic, man calm". It's just that I've found people to be persuaded to change their ways more when they're not yelled at or being ranted towards.
If OP was the one talking calmly and the man was the one yelling at him I would still say that about the man.
Edit: I also agree with you that people should be able to rant, but I feel it works against anyone who rants when the objective is to try to make the other side change their ways.
That's not what I am saying at all. Let me rephrase: I believe it is much more likely that whoever you're talking to will listen to what you have to say - and properly consider it - if you're saying it in a tone that puts them in a comfortable position where they feel safe.
This is anecdotal for my experience but whenever I was talked to in a calm manner I would consider the other side geniunely. When it was screamed at me (e.g. what usually happens in politics) all I think about is "how I make this person leave me alone". I don't care about the content, I just want this situation to end.
The end goal is to make that junior paramedic consider the perspective, and there are ways that are much effective to do that than rants.
