How have Samana Santa traditions survived modernism and secularism?

Felices Pascuas! I just came back from Seville and got to see the processions and all the amazing traditions of holy week.

What was fascinating to me is there doesn't seem to be much "tension" between tradition and modernity. Seeing young people with ear piercings and tattoos, even gay/queer men honoring the virgin Mary was very striking.

I'm from Ireland which was a very Catholic country, but has undergone rapid secularization in the last few decades. Such a phenomenon would be basically impossible back home. Being involved in religious events is associated with social conservatism, which most young people reject. It is also frankly considered cringe and uncool. This is not just in Ireland but I would say in most western countries.

I am curious why it is so different in Spain? People seem comfortable with modernity, feminism, sex, gay rights, abortion etc. But at the same time, are so devoted to their faith that they will carry a 50 kilos paso on their shoulder for 8 hours straight.
