I haven’t seen the pic so I can’t comment back.
But, in todays world, soda and water are in plastic, unless you buy one of the old school Coke bottles. Booze is in glass.
The pic was from about 20 years ago. But let’s assume it was beer - Desantis walks into a graduation party and one of the students has a bottle that looks like beer. If it was a graduation party, they are no longer his student - would it have been his responsibility to take the bottle away? But the point is that Trump and Trump supporters don’t even bother to research and find what is known about the picture, they just put out the slander, then object if Trump is subject to the same.
