Squid Vicious, their is something very wrong with you if the idea of being of moral character makes you sick.
This is how I look at it: You have just displayed character which I dislike and do not support. I will choose not to support you in your character, and I will distrust you because if you are unable to be trusted with one moral, how can I trust you with others? How do I know you won't steal from me, or cheat me, or lie to me?
Thus, if you ask me for help when you are sick, how will I know you didn't bring it upon yourself, and if you keep getting sick because of whatever reason, I will eventually be less willing to help you. Similarly if you complain you are short money for groceries and I spare some to help you, or offer out of my garden or chicken coup, and you continue to be short on money, I will wonder why. By displaying one set of immoral character, I wonder about your other morals, and will debate wether or not I will want to help you in your immoral ways.
That's how well-kept societies keep in one piece. This does NOT mean that you don't have the right to individual expression, as the other guy pointed out. If you enjoy Astronomy, enjoy it! If you like Music, enjoy it! If you like to garden, or persue whatever hobbies you want to, then do so! But, none of those are entirely societal issues. Music CAN be since it reflect culture, but I degress. The point is, that morals are about getting cooperation and trust from your neighbors and if you can't do that, you can't function. Simple as that.
