Boris, Что вы говорите? I mention this as Boris may be Russian, and having known Russians (and like them and Russian culture very much) there is a cultural undercurrent of disdain for gays and lesbians. This may stem from the Russian Orthodox church's influence, and it may have to do with a "macho" sensibility among Russian men in general. It is still not quite safe to be gay in Russia, even in major cities.
My own view is that as Buddhism can be thought of as a fact and science based practice, we should understand that a certain percent of any population will be biologically, neurologically, and psychologically gay. Born that way, the same as with other genetic and behavioral traits. Science has shown that gay people did not choose to be gay, but were born that way.
Having accepted the science, as we should as followers/students of the original great scientist of the mind, we can conclude that to deny gay and lesbian people equal rights under the law and due process is an offense against nature and the law. Of course gay people enjoy relationships the same way as straight people do; sex for romance,pleasure, intimacy, marriage. It seems to me very unethical, and very un-Buddhist, to deny any person the right to live ethically and happily the way that nature and their psychology intended them to live.
