(And really interesting in that regard, though I wouldn't want to have to deal with all these arbitrary rules!)
It seems to want chivalry plus equality minus morality. This desire is represented by factions who seem to work together on some level. The end result is a mess.
As for equality, women are far more at risk from sexual predation and assault; I don't think it's rude to let social customs reflect this by having them initiate touch, largely.
As long as you take proper precautions, it seems like sex is a good thing.
I like it, anyway
I guarantee you would get hundreds of reasons not just one.
Although they are probably gonna be "simple" reasons.
Maybe something like having the right to waive the Rainbow Flag in front of the Whitehouse in case of Russian immigrants.
Not really, it's also supposed to be unjust or harmful.
Can you see how that alone is harmful in some contexts?
Attributing strength and health to gender identity carries with is all kind of problems for everyone involved.
EDIT: I guess what I'm trying to get across is that it's not your gender or ethnicity that makes you treat someone a different way, it's who they are as an individual. I think that the idea of "chivalry" runs generally counter to this.
Reaching high boxes or opening jars is different. I'd do the same for a short old man as a woman, and I assume most men would do the same. It is no longer about sex, but about differences in people's strength and height. Gender doesn't matter as much, just ability.
Just like I'll hold the door for someone going through right after me instead of allowing it to slam in their face, or hold it longer for someone who's hands are full. I don't wait for elderly folks, though, since most folks are capable of opening doors.
Perhaps you are thinking "politeness", which is meant to be applied equally depending on other people gender, age, wealth...
The handshake rules are not necessarily prejudicial or unfairly discriminatory. Some of them might be, some of them might not. It's best to think of sexism, and other isms, as a spectrum, and not hard and fast rules.
Occasionally, I get a sneer from women. I assume it's an assumption on their part that I'm being sexist.
