What the heck does that third prong on a Western Hemisphere power plug do (the “ground”) if it isn’t necessary for all electronics?

Hell, I’ve even seen people rip them off to fit 3 prong plugs into 2 prong extension cords. I’m sure it’s not safe, but I dont know why and why they would be necessary sometimes and sometimes not.

Some items have their own protections built in that keep you safe when things go wrong. Those don’t require a grounding wire. Other items are not made with protections so the grounding wire fills that role … to protest people, pets, and property. Removing the prong is a frankly asinine idea that may not kill you or me, or even anyone you will ever meet, but it does kill plenty of people every year.
