How about the one about stepping into the gutter when a man is walking on the sidewalk?

I actually DO have a severe problem with this. The clothing ones may or may not be appropriate - each individual should decide for herself. The behavioural ones, though, are asinine. It's OK for a man to drink from a soda can but not a woman? It's OK for a man to talk on a cell phone wherever he darn well pleases, but a woman can not? A man can put taps on his shoes and go tap-dancing down the sidewalk, but a woman? God forbid her shoes make any noise.

And then they expect the woman to go out and slave to support her holy husband when he's 'learning' in Kolel...

Who said that those behavioral ones do not apply to men? In yeshiva, we were told not to drink out of a can or bottle, as it lacks refinement, and not talking on a cell phone in public any more than necessary is something that I try to practice as well (they didn't talk to us about that in yeshiva because no cellphones then :).

This looks like the results of a survey of things that individuals accepted on themselves, and not things that "you need to do".

"Pass a mezuzah" without stockings is one of those transitional things that people do when they feel they are not ready to change a behavior cold-turkey. Along the lines of, not speak lashon hara during a given hour of the day, or not eat x (name your chumra) in your own house.

I don't know about you, but I've NEVER seen a mezuza with stockings, they are all without!

I think the point is not about walking past a mezuza without stockings, but about being fully dressed, including stocking, when you leave your room. Going into an attached bathroom is OK, as is a walk-in closer, etc. Instead of listing exceptions, a "rule of thumb" is given. If you can't pass a mezuza without stockings, you won't leave your without being fully dressed.
