younger people don’t even take religion into account
As someone who hosted an Austrian woman who was asked by her (young) temporary work colleagues what my name was and then declared "oh, she's a Prod", ..... and then went to a bar with her and was asked by a young man in their wider group where i was from - and when I specified the area - he shouted "she's a Hun, we have a Hun here!" while pointing down towards my head from above ..
...... And also had young people who worked with my Polish ex (when they asked my name and he told them) tell him - again - "oh she's a fkg Hun".
Likewise I lived in a shared house with a young man, whose behaviour was atrocious and would take a separate thread to outline .. but when he found out I was a Protestant, decided all our problems of interaction were because I was a Protestant.
... I can't say I agree with you.
This was in Derry/Londonderry.
(Where all the protestants, except for one tiny enclave, moved out from the main city area between the 60s and 80s... because they didn't feel safe).
Ironically my late Grandmother was a Catholic from Donegal and we have an entire Catholic side to the family, including people whose family business is printing mass cards ......
But no-one I've met cares about that (or could even conceive of it), my name is "protestant" therefore I am a Prod and a Hun.
