Do you react or respond to things?
Modern life has changed our primal instincts.
Stimuli we used to choose to or not to respond to, now get a reaction out of us.
Someone posts something bad online, and we react with being hurt, letters to the editor and so on.
A reaction is involuntary, and a response is voluntary.
It makes more sense to react to the things that are a direct threat to us, and not respond to those that aren’t.
