It would block it all the same if they parked in the spot. Assuming this person is handicapped themselves they must’ve figured “either I block the entire parking spot for everybody, or I block it only for those that need the loading bay area for a wheelchair lift.”
I honestly think it’s meant to be courteous and it does work out that way for some if this person’s only alternative is to take up the whole space.
I can see why you call it disingenuous but the point of the matter is that children are getting shot. You can break it down into as many catagories as you like, the bottom line is that far too many school aged children are dying violent deaths in a world that has enough knowledge and resources to know what the solutions are to prevent it. The only thing keeping that going at this point is political fuckery.
