I wouldn’t cut the kid off from home, but it would be understood his butt buddy wasn’t welcome there.
I wouldn’t be giving wedding receptions with all of his pervert friends there with my family and would make it clear that because I loved him I would gladly pay for help with his sickness.
If there’s any indication the kid wants help or isn’t ‘convinced’ f his problem, then I totally agree. Help all one could possibly do. But if they are in you face “Gay and Proud” Then that’s their choice.
As a side note, you brought up weddings etc. The selfishness of the homo results in nothing but chaos for the family when it comes to family events as well. Think about ‘the one’ regular ‘problem child’ EVERY family has at least one of. Christmas, weddings, BBQs ... all of it. If there are 100 people at the event, 90 of them are on eggshels because no one wants to ‘ruin it’ for everyone by saying something when the probchild has his/her attention grabbing scene. Or most likely, many AVOID family events BECAUSE of these types.
My family had several of the regular type and it was hell. The selfishness of these people is boundless and when Homo is thrown in the mix it multiplies by orders of magnitude.
No good EVER results from homosexuality and catering to it. But a lifetime of pain and suffering for everyone involved does.
