It is not my responsibility to "take a beating" from anyone no matter how well I might be able to absorb the punishment regardless of what age, sex, race or creed or national origin they may be.
Ohio has a "brandishing" law and if the intent of a charging mob wasn't perfectly clear, within the law I could place my hand upon my unexposed weapon and let the mob know they were threatening me and that should they come closer, I'd defend myself.
Further, I'd risk the brandishing charge should the mob continue to close by presenting my weapon and repeating my warning, if there was time. Firing a round safely into the ground might help, but it might hurt in court, portrayed as a reckless act.
It is not in my abilities to read the minds of the members of the mob and discern their true intent. If I believe they are threatening me and lethal force is needed for my self protection, I will use it and do so with moral certainty. I'll face the legal consequences, if any, after I've survived the threat.
If you are not sure of the extent of the violent intentions of a charging mob, you are free to risk life and limb to give them the benefit of the doubt and avoid the legal consequences. I'd discuss it with your wife, though, to be sure she is just as willing to get kicked and beaten and maybe killed for the sake of not misunderstanding the exuberant youths.
