If by mad you mean insane or crazy, it is impossible to tell, since being abnormal first requires normality - you can't say it's broken if you don't know when it is fixed or working either - and we don't know what the mind of any god is really like.
If by mad you mean angry or displeased, then any negative event that happens to you (you lose your keys after saying "God damn it, I'm late"), to someone you know (they get in a car crash after hurrying to pick you up while you are late), or to humanity in general (an earthquake or tsunami destroys the city you live in on the day you are late and cursed a god for it) would be a good sign of a deity's anger.
Sin makes God mad and angry. Whenever, we sin got get God mad.

No. There is no logic in thinking that God created gay people and then became mad at them for being what God created.
