Worse it equates words to actual physical pain, they aren’t the same.
This is something which needs to be reiterated, because people keep putting forward the idea that you can compare physical injury to emotional upset, overlooking the salient ways in which they're different. The big one being that things which cause physical injury are discrete, where things which upset people very rarely are.
The example I like to use here is a friend of mine who likes to play a lot of first-person shooter games online, typically against other players. There's a lot of trash-talk that goes on in such matches, most of which wouldn't be at all appropriate in polite company, but he and most of the other players (from what I've heard) let it roll off of each other's back.
One time, however, my friend completely lost it. From what I heard from his wife later, the insult wasn't one he hadn't heard before, but this time he started screaming at the other guy and almost threw his controller across the room. To hear that on its own, you'd think that it was that the use of foul language had finally set him off, that it was
always a problem, etc.
What it actually was (again, according to what his wife said later) was that he was under a great deal of stress at work, because there was a round of layoffs that were approaching and he was afraid that he was going to lose his job, and with it the health insurance that his son, who has special needs, relied on. That had absolutely nothing to do with what happened in his FPS game, but
that's where his anxiety, stress, and resultant anger were released.
So no, someone saying something that you find upsetting is
in no way equivalent to them stepping on your foot, accidentally or otherwise. To put forward that it is makes for a bad analogy that misrepresents how people operate in the real world.
