I don't doubt for a second that that's what you see...a mess, unsanitary crap etc.  The thing is, you could see things from another perspective.  For example, you could see human beings as opposed to a mess, unsanitary crap.  The failure to see each other as humans beings and the notion that the "right" of one person to not being subjected to seeing what they deem an "eyesore" superseding human life in and of itself is a fascinating thing.  It's why people protest suicide barriers on bridges, even though we know they save lives, people get upset about their scenic view being disturbed, it's why people cry for "men's rights" as a retort to the notion that a woman's body is her own - because they don't even want to acknowledge that women are equal, it's why people complain that they're tired of hearing about racism without thinking how it must feel to live with it everyday.
