It could be. It seems not just difficult but actually against most culture on the planet. Consider that crimes of passion, like killing someone when you find them sleeping around on you, often get a lower sentence than a murder 'in cold blood'. If someone says 'he made me angry' we know exactly what that person means. Responding to a word with a bullet is a very common tactic, even in a joking situation; I've had things thrown at me for puns!

It does seem like a learn-able skill even so. I did not have this skill when I was child, but I do have it now. The point I learned it in my life seems to roughly correspond to when I was first trained and working as technical support. I don't know if there's a correlation there.

In any case, merely being aware that this is a skill may help a few people on this forum to learn it, and I can see only benefit in trying. It is possible to not control anger but instead never even feel it in the first place, without effort or willpower.
