Reading books is just another way of wasting the time, a better one. This doesn't mean that books should be considered as a bad thing. I'm thinking about the TV or the internet which have more cohorts than reading.

I don't think they're happy when they're doing all the things you're talking about. Most of them do things that turn the others, which are not a good thing for the rest of society, and they're conscious of the fact that they are not doing a good thing. If they seem to be happy it's likely to have a mental problem. As long as you don't hurt others and you accept you as you are then loving another man is certainly not a sin.

Fado... I've descovered it recently and I'm still amazed by it.

I agree. I've changed it.

If you do what you really feel that you have to do, it should not be a problem. While you know what you do and you have consciousness to decide then you should be happy with your life. All that make you happy should not be sin.
