Not sure if all of these are double standards. Let me see.
"How is it that a woman can look at another woman and say, "Wow! She's beautiful/sexy/gorgeous/pretty!" and nobody thinks a thing about it. But when a man looks at another man and says, "Wow! He's gorgeous/sexy/handsome/good-looking!" everyone will look at him funny?"
Well, I've never had any qualms about saying if I thought a man or a woman fit the above descriptions (I'm a guy, by the way. And straight.). I also could give a hoot if someone thought I was gay because I thought another guy was good looking. don't we all appreciate beauty? When I see a guy that I think is particularly good looking or sexy or charismatic, I also may find myself studying him to see what it is that sets him apart from other men. I find at times that it is not always the looks. Same with a really sexy woman. Interesting looks with a certain air or attitude is a remarkable combination. And I don't mean arrogant - which is a total turnoff. Confident and friendly are a deadly combination. Add intelligence and humor and you have the ultimate weapon.

"Why is it when a black/Oriental man is proud of his color and ancestry it's considered national pride, but when a white man is proud of his color and ancestry it's considered racist?" There is some truth to this - but I think it's part of the culture right now. No easy answers on that one.
"Why is it when a woman gets a divorce she's considered a "divorcee", but when a man gets divorced he goes back to being a "bachelor"?" Sorry, I've never thought in those terms. Divorced or married applies equally to men or women, from what I've seen. I almost never hear anyone referred to as a bachelor anymore. Ever. And NEVER hear the word divorcee. Single is the word I hear, and again used for either sex.
