Some things that count as churches may have sprung up to make such offers, but I am assuming most churches have been standing since before Covid, before Facebook, before Trump and Obama and Bush.
If say 40% of people are attending these gatherings, it's a tough sell that they are so far from mainstream as to be countercultural.
People have been visiting churches in search of unity, security, and joy for thousands of years.
Traditionally, they say that because even when their outward trappings are all over popular culture, they know that their core message is difficult to live out in practice, and most of the people who show up aren't doing it.
