Funny thing, when I transitioned, I worried what members of my church congregation would think or say. For some reason I felt the older folks would be mostly against me now presenting as a woman, while the younger generation might be more accepting. Wow, was I wrong - the complete opposite.
The older folks have 100% accepted me, and one lady likes to sit with me in my pew. She's such a sweet lady and in her mid 80s.
When I first came out, I was surrounded by 5 or 6 ladies who encircled me during coffee and wanted to know everything. I doubt one of them was below 70 years of age.
I jokingly say the reason for this acceptance by the older folks is their eyesight must be way off if they accept me

Now the younger people, the ones with children, they seem to be a little reserved. They treat me nicely, but not even close to the feeling I get from the older ones.
I think you'd be surprised how accepting older people are.
