No, what I'm saying is that when there is a known risk to you of engaging in an activity with other people, it's up to you to decide how you want to handle that risk, either by taking precautions, choosing not to engage in the activity at all, or whatever works for you.  But you can't expect someone else to be saddled with the burden of the risk that YOU take with yourself.

The guy who kicks me in the crotch is just going for the ball; he has no obligation to me and my safety in a game that I willingly participate in.
