> Obviously if you spill a hot drink on yourself your going to burn yourself. If I sell you shampoo with hydrochloric acid in it, and some gets in your eyes and you're permanently blinded, should I be held blameless because "obviously getting soap in your eyes hurts?"
It is my right to buy shampoo with hydrochloric acid in it without the nanny state getting in the way. Sane adults don't blame someone else when they put hydrochloric acid in their own eyes.
It may be your right to buy hydrochloric acid and to pour it over your head, but actually, that's wildly different to what you said.
