You don’t give up on your kids, but you also don’t give in to their harmful and self-indulgent behavior. Gay children should not be made comfortable in their open, willful, harmful, and sinful activity. They want “normal” family time while indulging in unnatural and abnormal behavior - all the while demanding their family remain silent and while warping the minds of young family members. Too many parents coddle and give comfort to their spoiled and narcissistic children thus further the child’s self-destruction. Sometimes, the best way to show a child you care is to refuse their immediate wants.
It's important to let them know that you don't condone their behavior, but you still love them. If you set up the stop being gay or I won't love you anymore scenario, the kid is lost to you forever and even more destruction is on the way.
Now instead of the tough love parent you become the reason for the behavior in the young person's mind. That's not fair to you as a parent. You should not have to be made the cause of their disorder. It's not an easy thing for anyone.
What is more or at least as frighting to me is how will gay "parents" react to children who grow up straight and reject their "relationship". Get ready for that.
That being said this is one sick and twisted world we are living in and I don't envy anyone trying to raise kids in this environment.
