Only the male of the species would think that blocking a common pathway was grounds for arrest or assault. Watch women going about their business in the neighborhood supermarket. Women are constantly hanging out in the aisles without pulling their carts over. They'll stop on a dime to reach across the aisle to grab something without regard to who's behind them or coming the other way. It's a lot like a MUP. Yet, they don't get mad. They don't seem to even acknowledge that there's a problem. Someone stops in your way. Go around them. Someone's blocking the aisle. They'll move without so much as a comment. It's a different planet. Who are we to decide that MUP behavior should be closer to that of a highway than a supermarket?
