Triggers are only real for the people who are triggered by them.
This is why they're mocked.
In one description I read, "Tragedy is: I have a hangnail. Comedy is: you fall through a manhole cover and die."
Mocking other people's pain is a way to cope with our own. That's why you see the term "triggers" used in a lighthearted or cavalier manner. I'm sure there's a large portion of the population who would have seen my 80-something WW II veteran father dive for the ground at the crackle of thunder as the most hilarious thing they'd seen in at least a week. And I've had many people telling me, throughout life and also lately, that I'm overreacting, being too emotional, being a victim/martyr/whiner or "giving my power away".
This form of casual brutality is like poison. No bruises are incurred, no guns go off, but there's injury on the inside.
Just an FYI. Mocking a trigger is in itself a trigger.
Please remember that before you fire off a little lighthearted snark.
