I have a cousin that is without a question homosexual (I'm not a fan of the word "gay" - personal preference). When I was very young (he's 12 years older than me) he was going thru issues regarding understanding himself, married a woman, who actually helped him understand who he is and that he was born that way but forced into an expected life style. He is now very happy and they are still great friends.
He never painted his finger nails (I asked him)
I have another counsin who is without question very Heterosexual. he currently engaged to a very nice young lady. However before her he was quiet the ladies man. As children he played dress up, house, school, make over parties and all that with me and never had a problem or thought it odd to dress like a girl, wear nail polish or make up. He actually insisted that a picture we took on my aunt's camera of him in my summer dress and make up when we were 8 yrs old should be posted on his graduation party picture colage and I believe its on his facebook.
Our society as a whole is superficial, ignorant and close minded. Painting your finger nails or toe nails does not indicate you have gender issues or that you are homosexual. Wearing a dress, skirt or blouse does not indicate you have gender issues or that you are homosexual. Its of the mind and soul. Its how you are born. The true tragedy is that society and parents (like my aunt) are so intolerant of anything outside of social normality they condem their own children, the next generation, to a life of misery.
I only hope that by the time my grandchildren are born this society has learned that the pendulum needs to swing both ways to restore balance and peace.
