My mothers side of the family is/was from Northern Ireland, I waited until my grandparents had passed away before coming out, I loved them to bits but have very strong doubts that they'd accept me.
My mum has this Irish view ingrained into her that me transitioning is a form of social shame, she's happy to go shopping with me but I only get invited to her house when her exchange students are away/home.
When my auntie passed away my mum dropped repeated hints that as i'd not seen my auntie for a few years there was no point in going to her funeral but it was obvious that she didn't want certain distant family members from knowing about me being trans.
Now for the flip side of the coin, I spend a ridiculous amount of time on my Xbone & a great many of my friends on there are from various places in northern Ireland, they all accept who and what I am & support me.
They have supported me through depression, they joke with me in the good times, they get very angry when I mention having been abused that day/week. If some of them don't see me online for an extended period of time they'll start sending messages asking if i'm all right.
As with every walk of life there are good and bad people, sometimes it's not as simple as good & bad but more a case of educated & uneducated.
As we move through time the educated will outnumber the uneducated, the outdated views will fade & vanish like a morning mist. The sheer force of public perception will one day render any negative views to shrivel & die.
