In some home-schooling families I know there are five boys or nine boys. If he has a loving, supportive, encouraging, positive relationship with his older brother, that's a very good sign. Whereas, if it's a feared, hostile relationship with the older brother, then that is not a good sign. If the younger boy shies away from his older brothers or feels intimidated by them or is constantly being beaten up by his older brothers, that's also another important variable. Freud said 90 years ago that if a homosexual has an older brother, it's a feared, hostile relationship with the older brother, and I have seen this to be true time and time again.
Many people have a family member or neighbor who is homosexual.
I don't want my kids to be un-Christian, but I don't want them to think it's normal. Basically, we should educate our children to see that the homosexual is a person with a problem. We have to respect this person. We don't want to contribute to their unhappiness by rejecting them or making them feel bad about themselves. We have to always be Christian and tolerant of the person.
