Yes, there have even been studies that show that when people are given even a little power, they begin to act differently toward others who are "lower" than their own position.

The fact that anyone could be offended by such advice is beyond me.

After reading the piece, I'm inclined to say that the feeling of being infantilized when someone says,

“Watch your liquor, ladies. Don’t drink so much, girls,”

is more a product of being reminded of something the writer takes to be implicit.

For example, I get a bit annoyed when my mother tells me to be careful when I'm doing something dangerous. I already know it's dangerous and chances are, I've already taken precautions and hearing her say it wouldn't help me out even if something did go wrong, though it does then enable her to say, "I told you so."

I can only imagine what it would be like if people often took it upon themselves to remind me that every time I went out to a party, there was the possibility of rape.

That said, I think this piece of writing needs some work.
