For me the issues around homosexuality are not necessarily that there are people out there who prefer to have sex with people of the same gender. I say screw whoever you want, if it flicks your switch, do it.
There are many gay people who go about their daily lives with a minimum of fuss and fanfare. They have happy long term relationships, hold down jobs, buy houses, and have little bearing on this debate because they are so "normal" we don't notice them.
Then there are the "activist" gay people who espouse a desire to be accepted as an integral part of society and yet exhibit the kind of behaviour that serves only to exclude them from "normal society". They insist on gay arts prizes, gay marches, gay footy teams, gay clubs and bars etc etc ad infinitum. They effectively segregate themselves from the mainstream whilst criticising it for failing to embrace them.
These people I have an issue with. (not because they are gay, but because they are stupid, like treehuggers)
As for the ubiquitious Arts degree... I think the whole point of them is that they are study for the sake of study. I fail to see how we, as a society are worse off for a better understanding of the disciplines contained in an Arts degree. Granted, they are of no direct commercial benefit, but they may help shape and influence the way view the world, given a more comprehensive understanding of it.
