For example, person A says something not directed towards anyone in particular, but it was a criticism nonetheless, and it was intentionally meant to indirectly tell off some people.
Person B takes offense for whatever person A said, thinking that it was meant for him specifically; even when it was supposed to be for a group of people (which he may or may not be part of).
What has person B done, or what do you call the act of already claiming that you're guilty, even when the criticism wasn't for you alone?
I think I've come across an idiom for this sometime ago, but I can't remember what it was, nor where I found it.

In this situation I say to the offendee, "If the hat fits, wear it". Related when people think you're getting at them when in fact you aren't (slightly different from your scenario), the Biblical line, "The wicked flee when no man pursueth".
