Are Catholics actually still doing that? My understanding is that the pope condemned it over a decade ago, major changes have been made, and while it was an institutional issue, it didn't go straight to the top.
Where do you draw the line? What companies are you boycotting due to their use of slave labor, etc.?
Obviously, when you've been personally affected, that's a pretty easy line. I've got my own list of personal boycotts for similar reasons - but I don't expect you to care, and I doubt your list includes many of those names.
I'm not a fan of the Catholic Church, I just dislike the idea that one cannot possibly support any organization which has, at some point, in some capacity, done something wrong. Pretty much every flag and religion has been used to justify atrocities. Mega-corps aren't doing much better. Buy local, abandon globalism, I guess? But then why are you on the internet?
