That's because they see the lack of full-100%-no-questions-asked support as a lack of love...they are like defective children, they equate things that are not be equated...when a child clearly misbehaves and is admonished by a parent, the parent doesn't stop loving the child, nor does the child stop loving the parent (they may be really ticked at them, but, tough!)...these people refuse to grow up and expect their family members who disapprove of their behavior to suddenly and miraculously declare "You know what? You like being face-deep in another girls crotch, that's fabulous, tell me more about that!" or "So, you like taking turns taking it up the ass, how splendid, lets talk about that some more, OK?"!
Seriously, the are unable to get over themselves and blame others for imagined problems.
Best thing to do is ignore their antics and if necessary ignore them as much as possible.
That's the thing though. They want everyone to endorse the homosexual lifestyle, merely "tolerating" or ignoring it is not enough. Most people can't, even when it involves a family member. Most gays forget that most people find the idea gross at minimum.
I know it was that way when my cousin came out as a lesbian. The family of course didn't like it and was unhappy about it. It didn't help of course that she was militant about her new lifestyle. So she basically cut off the family for a number of years. Then she had a test tube baby with one of her "partners". When she found herself a single parent at that point, she finally started to grow up a little.
Now, you have to keep in mind, we aren't a family that is going to shunning her, and her folks wanted to know their grandbaby even though they weren't happen about how she came to be. Shunning never works anyway, and likely drives the militancy because it puts it in their mind they are being discriminated against.
Slowly she came back into our lives. We can tolerate that she is gay, there is likely nothing we can say or do that will change her mind about that. She no longer tries to make us endorse the homosexual agenda, because she knows it isn't going to happen. She doesn't bring her partner to family events. And she seems to be OK that her daughter is straight. Seems like a truce has replaced the anger of it all.
I wonder if the gay movement will grow up or not? Seems doubtful at this point. It has to get over the fact that the homosexual agenda will never be "mainstream" no matter what "laws" or rules they force on society.
Thirty years ago, most gay people didn't even want "marriage" and nobody even remembers that. It seem excepted in the gay community that gay partnerships were not marriage that they were something else. What changed with that over the last couple of decades? They seem more interested in destroying Christianity since they are the only ones standing up to the nonsense.
I imagine the Cheney's have the same issues with that family member like we did. Some people take our live and let live toleration of our family member as supporting the gay agenda. We don't support the agenda one bit.
