Gay people can be the absolute pits sometimes.
No, coming out should NOT be a big event. It should be accepted as something completely normal like hetrosexuality. We shouldn't have to 'come out the closet'. You don't have straight people 'coming out the closet'. It's not a huge event if your son likes women, so why should it be a huge event if your son likes men?
