You think gay people don't like money or that big banks work against the interest of gay people ?
I'll tell you a secret, in big corporations, gay people are many, don't hide and are sometimes in power. They celebrate pride months because they care, they're the bosses :D
And it's perfectly fine :D Sexual minorities are often oppressed by traditionalists and uneducated people, and a coke addict stock trader is quite the opposite of that.
