Although I'm not gay, I consider myself strongly in the supportive camp, and I also know what it's like to live in a judgemental family dynamic of intolerance.
The best answer is one you've found. It is better to be away from that than be around it, whether they know about the real you or not. As you implied in your year-ago article, you were getting subjected to verbal abuse even though you weren't specifically targeted. Being around that isn't good for the soul.
I "decommissioned" the majority of my family a long time ago for its intolerance and (more so) its general dysfunction. No regrets, other than the occasional pangs of jealousy when I see what I interpret (correctly or otherwise) as happy family moments out there in a world we don't really know.
Good luck! I hope you find your new family soon.
