I will rely on Jack Posobiec (https://x.com/JackPosobiec) and J.D. Vance for the resolution. Both are practicing Catholics vocally critical of the far left activist Bergoglio.

They must consider the new pope's overall policies as based (not necessarily, but preferably using that word), it is not sufficient that they refer to any single specific thing the pope does as based (though it will be a strong indicator that the pope is, in fact, based).

You may consider Vance's Munich speech as the gold standard of basedness.
