First off, The purpose of sinks are to clean ones hands or prepare food/clean dishes. Im personally not a fan of pee flavoring. Also you’d be amazed at the mineral and scale build up in urinals… peeing in your kitchen sink, which is already most likely on the verge of clogging due to food/grease, will make it clog up quicker.

Also also, if i pull the trap on your piss-clogged sink and get soaked in that piss and all the nasty food gunk thats also in there…imma be pissed.

No one is peeing in the kitchen sink, this is referring to your bath sink. Plus urinals are quite dirty because a lot of people piss there and don't flush it because the piss goes away and it's a public bathroom so people probably avoid touching as much stuff as possible. If you flush there's no problem. And once again, you're focusing way too much on the kitchen sink
