Like most things it's not a simple matter, but a complex and nuanced one, too much so to say it is either all good or all bad.
I think, it origin, it can be boiled down concisely to this comic.

Which itself can be boiled down to pendulum swinging.
As for the hypocritical and cringey behavior, we have to account for the relatively new reality of social media. Individual shortcomings, misguided interpretations of morality, and the normal process of making mistakes in the pursuit of personal growth; these are all things that used to be relatively private and are now on public, world wide, display with seemingly permanent records.
Take the individual who inspired this discussion, Tacktical Templar. I can say from observation that he has an incomplete understanding of Catholic theology, and that he is clearly plagued by the sins of lust. Because these things are blatantly broadcast, it is easy for us to label him a LARPer, and accuse him of being duplicitous or insincere. While those accusations might have merit, and might be necessary to push him towards real virtue, we need to remember that only God can know a man's heart, and temper our judgement accordingly.
But that's nuanced, and, unfortunately, nuance doesn't sell. People want simple, pragmatic answers to everything, and they get disappointed, or even angry, when those answers don't exist.
