Thing is, saying "the pope has done multiple bad/harmful things that I think make him a bad person" or "the power the Catholic church itself wields is/has been used to do a lot of very harmful things" is not bashing Catholics. It's not "nyah boo, Catholics suck". It's criticising things that have been done. Actions.
If anyone receives spiritual or emotional wellbeing from being Catholic, feels their Catholic faith is important to them or the like, I don't think anyone who's commented here would criticise that. But the Pope is a man who has covered up for child abusers and pedophiles for years and has promoted a campaign of hatred towards LGBTQ people that, in countries where the church has more power, has had a devastating impact on the emotional, mental and physical wellbeing of millions.
Saying he's not a good person, or that the church as an institution is not currently a force for good, is not bashing individual Catholics. Any more than saying that "Asatru has a big problem with racism" is bashing my Norse beliefs. We do have a big problem with racism. And it is something we need to acknowledge and deal with.
I'm not glad a person may be in ill health, but I am glad that a person who has used a position of power to do great harm is stepping down, even if I'm not terribly hopeful that his replacement will be any better.
