Hide the camera in a drawer, in a locked cabinet, in a dark room. Very stealthy. Place it in a paper sack, with holes cut out for the lens to protrude from the front and for your eye at the viewfinder. Carry it like you were carrying a pint of cheap hooch. Also very stealthy. Carry your camera under a rain coat, like a flasher, opening the coat to scare people as you snap. They'll be preoccuppied with the threat of being flashed and will never remember whether or not you had a red dot, black dot, covered-with-gaffers-tape dot, no dot, pink polkadot or were carrying a Kodak Instamatic.
I've had no dot, red dot and black dot. Seems to have had no impact on my results. Aesthetically, I liked no dot best. No offense intended to anyone, but IMHO, I think this whole thing is silly. One of my favorite cameras posted on RFF by another member is his (can't remember who you are) hand-painted, red MD. I love the kitschy irreverence of that. And it looks cool, too.
Check out the YouTube vids of Gary Winogrand out shooting. He rubs the camera on his face (an M4, btw) while deciding what to look at. He treats it, as Al says, like it's part of him. Like many things, if you believe something, it almost becomes true. Gary treats the camera like an extra finger and it nearly becomes one. Then, he gets to his office and rather unceremoniously plops the Leica into a file cabinet drawer (also containing dozens of rolls of undeveloped film). He does lock the cabinet.
I treat my gear with care only because I can't readily afford replacements or expensive repairs. My gear doesn't rise to the level for me of religious icons or relics that need to be treated with obessive reverence. It's a tool. If the gear were paying for itself and all my bills, I'd be less concerned about how it looked. It's a tool, not a fashion statement.
