Is there any secular reason why being gay is bad?

Read again. Society has no place chastising you on many accounts. Non-disruptive public behavior is one of them.

Well, if you are not distruptive, you're not chastsized by the society.
Homosexuals who live out openly, and demand extra rights for themselves, distrupt various things.
It's not exclusive to them however. Obviously, religious fundamentalists do this too. They are also, very distruptive to how society should work out.

No, actually, such a society would be above its base needs. Its your kind of society that has the nature of an animal. Something that apparently cannot control itself and has to be beaten into place by the stick of public decency.
And you last argument seems to be "They'd do it too, so its okay if we do it". Well, your forcing gays to act straight is wrong, just as them forcing you to act gay would be wrong.

The nature of an animal?
We control ourselves, friend. We do not need the police to force us into a line. If you cannot, maybe you need a wife or a mum to help you with that.
Whatever I do, or the society does, is not wrong. It is just the way things work.
It all comes down on how you accept it.

Apparently, he didn't get through to you, since you are repeating the same old tripe.

I am repeating myself due to the fact that you make me repeat things.

You are forgetting the third option - don't give a fuck. For example, I don't give a fuck about living in harmony. When and where its convenient for me, I'm open to "harmony", when and where it isn't I don't cooperate. You know what protects me from the "wrath of the public" - my rights.

There is no such world, friend. If you do not want to live in harmony with others, you obviously will run into people. You will step on toes. If you are un-cooperative with others, even the law won't protect you, for the law must be in harmony with the people. No law that has not been in harmony with the people survived to this day.
