I would go a step further and say religious parents have a much more inclination to reject their gay children based on religion rather than if they are irreligious.
I suspect you believe rejection of homosexuality and rejection of the child is the same thing. It is not. But I will not argue, because then I would be wrong, that some people do reject the child and that is a tragedy. The only time a person should be rejected due to their sexual desires is when they refuse to fight against the flesh, as we all must do, and demand acceptance. At this point, they have turned away from God and toward them and the only thing at this point we can do is pray for them. For instance, do you think an Orthodox priest would ignore two grown men or women holding hands in church and kissing each other? No, he would tell them to stop or not come back, as he should. He also would not allow communion until they went to confession and asked God’s forgiveness of their sins, as he should. Is he being a hater or being a servant of God?
But yes, those few parents who immediately kick their kids out of the house for saying they are attracted to the same sex are wrong. A parent’s job is to help their child as best as they can, regardless of the sin they practice. If the child is older and rebels violently against the parent, that is different and I would remove them from the home as well. Not allowing their boy/girlfriend over, on the phone, on the internet, etc., is not hate, its parenting. I do not know if you have children and if you do how old they are, but most parents understand this concept very well.
To answer your question, what would I do if one of my children said they were homosexual, I would do everything humanly possible to help them overcome their sinful desires while letting them know I love them unconditionally. To follow up with what I was talking about with my brother…he wanted to visit when he was still with the aforementioned partner. I told him they were both welcome, as long as they slept separately and didn’t display any action which would confuse my children. They both, of course, agreed and we had no issues. It isn’t about hate, and you well know this. It’s about right and wrong. Nothing more.
I know two close friends of mine who were scorned because they are gay, and it had everything to do with religion
Scorned? This isn’t very specific. Being belittled is one thing, but being told they are wrong in their wants of the flesh is entirely another thing. Remove the word “homosexual” and replace it with any other unacceptable behavior and see if your argument holds. Adultery, fornication, drug use, alcoholism, sexual desires for children or animals, worship of money or any other false idol to include ones one person, pornography, etc. The same argument does not hold, so why the exception to what people want to believe is ok, but know it’s not?
