I believe you are likely right. Maybe not totally alone, I've met and know a tiny, tiny number online like me ... But practically alone in RL, and mostly online.

It is a terrible shame. Loneliness and even invalidation is one thing ... But to constantly have the lying carrot of 'acceptance' or 'welcome' dangled in front of you, while watching many other groups get tolerance, even endoresement, is just galling ... Hope is a source of disappointment and pain.
