This is some weird goalpost moving - I didn't say it's easy I said it's possible. Contrast with the fact that you fundamentally cannot question religious ideology - it's literally against the rules.
Martin Luther was pretty successful in his questioning.
But I guess he did get excommunicated for it, didn't he?
Well, I guess that could easily be described as "not easy".
But luckily, I'm not Catholic, so I have no idea.
Obviously 'Not all religions,' etc. However the Catholic church is notoriously dogmatic. Usually the more you press a dogmatic group to change, the more they dig their heels in about it. It's only when the organization is wounded by a schism or massive loss of membership do they suddenly start getting word from heaven that God has changed his mind.
Your lack of answer to that question speaks a lot.
This is wildly underselling the consequences of challenging the church: two centuries of unrest and war that would eventually result in millions dead, amounting to a significant fraction of Europe's population.
There are lots of different bible worshippers but there is only one academia. There might be small differences of opinion they all preach the same "proverbial" creation myth.
Most history taught in the states already waters down the historical facts to make us look better.
This feels like an odd statement, given how many of the most repressive regimes in human history were or are secular. Maybe the "properly functioning" part is doing the heavy lifting, but if so, it makes the statement almost meaningless.
People say this all the time and it's facile. Yes ideology is everywhere and you cannot be completely free from it. But the critical difference between secular ideology and religious ideology is that (in a properly functioning society) you can challenge/question/probe secular ideology.
