In my book, throwing a son/daughter out of the home has already shown the parents’ failure. Such action is nothing but washing hand in the name of ‘saving the rest of the family’. The parents simply cannot deal with their own issue, i.e., the shame of failure in raising their kids.
But again, it depends on how old the kids are, and whether they have talked it out thoroughly.
Homosexuality is what St. Paul would call ‘thorn in the flesh’ for Christians. Something that is perennially stays with the person, regardless one’s belief whether it’s by choice or by birth. The same applies to the person who has the tendency and his/her parents/family members. St. Paul said he cannot get rid of it. He just needs to deal with it.
So it’s sort of like a drug or alcohol addiction then, would you say? A desire remains, which must be controlled rather than indulged.
Not an easy life, I’m sure, once a child has been introduced to it. All the more reason why children must be protected from any and all exposure to it - also not an easy thing for parents to do, without cutting their families off from a large portion of society. If they fail at that task, life is going to get really hard for both parents and child.
There are countless former homosexuals. There is help but of course homosexual activists hate that fact like bitter poison and young people may not even know of such help.
