To me, the kiss is a male power put down.
Why? If women gave me a kiss, but only shook the hands of other women... I would not see this as some female power play.
There are gender differences in society. They are cultural and natural. Sometimes they deal with the real differences between men and women, sometimes they are designed to offer guidance on courtship and attraction in social situations, sometimes they are just tradition.
But what harm does it do? There are plenty of similar traditions where men are treated differently than women in society. How many of these would you get rid of?
- Dating tradition where men pay for a woman's dinner.
- Engagement rings (where a man buys an expensive gift to show commitment)
- Flowers (there is no equivalent gift to express affection to males)
- Holding a door open or offering a seat (it is rare indeed when a man gets offered a seat).
- Self restraint on language (I speak freely among men, I tend to hold my tongue around women.)
I am fully supportive of real issues-- equal pay for example. But cultural traditions are just traditions. There is no real problem here-- and perhaps there is some ancient wisdom behind these traditions.
