@jesyka, according to your posts, he did not offer an invitation for you to go backstage. And, he did not coerce you to look at him. You stood in a place up front of the stage, where he was in full view. You chose to stand there. How were you coerced? You have an imagination that runs wild. This man did not assault you, he did not extend any invitations, there was no imaginary rejection, and he did not coerce you.

I also think of "rock star" as a national well-known actual star. Yes, this band has a large following, but a true rock star is well-known in all circles, is famous, and is treated like a celebrity. This is a musician with a large following who plays in small clubs.

I get that you're trying to figure out why these things happen since you state there is a pattern.

You were up front, this musician likely assumed some things about that, and he did what he did. I don't think you were any special kind of target. He may have done that to any female standing right there. It happened to be you.
