Sex, gender and sexuality

According to my lecturer, the 3 words have different meanings. Sex describes the bodily structure, gender describes the behavior and sexuality is the preference. In ancient times, it would be difficult to grasp because all 3 aspects should equate, i.e. man behaves like man and prefers women. In modern day, however, it is not uncommon to see a variety of combinations.

Man behaves like man prefers men, eg macho gay.
Woman behaves like man likes women, eg butch.
Man behaves like woman prefers men, eg sissy gay.
Woman behaves like woman likes women, eg les.
Man behaves like man likes women, eg MVP.
Woman behaves like woman prefers men, eg classical lady.
Man behaves like woman prefers women, eg SNAG.
Woman behaves like man prefers man, eg Tomboy.

To complicate matters, people no longer follow the binary system anymore. They stand on different segments of a wide spectrum. You can be 40% manly and 60% girly. You can have breasts inplanted while u keep your penis. You can like both men and women (or even animals and objects for that matter).

The question is, with so many different types of people around, should we be totally liberal and accept everyone's behavior and preferences. Should there be a limit to the level of acceptance we can give.

For example, it appears that many people think that homosexuality should be accepted. They tend to compare Singapore's restrictions on homosexual activities with countries like USA and comment that we are not that liberal yet (YET??). Do we really want to be that liberal? Many blogs are bashing homophobes and that is really worrying.

I personally think that homosexuality shouldn't be promoted. Firstly, based on their logic that everyone is entitled to behave as they like, they shouldn't be bashing the homophobes for the very same reason. Furthermore, does it mean that people having fetishes for beastiality should be allowed to carry out their fantasies even with the consent of the animal? That logic is flawed. Secondly, I think it's still Ok for gay couples who can't help themselves to be together. I'll see it like alcholism or compulsive gambling. However, there're so many gay couples who are standing out and fighting for rights. They want marridge, they want gay parties, they want gay movies they want gay porn they want gay rights. This isn't a problem of two individuals anymore. What if kids in the future think it's not cool not to be gay, just like how they think it's not cool not to have sex in many parts of the world that are too liberal. Can you imagine the outcomes?

To conclude, people shouldn't be judged on what they wear or how they walk. Sexual preferences and work capabilities are 2 different matters and members of the queer group should not be discounted when it comes to work. However, homosexualism should be regarded as a problem and we must always try to reduce and not promote it.
