To me, that’s a pity as I’d love to hear the dissenting views and why they hold them but I understand why that those who hold them are too reluctant.
This forum, with its “Catholic” branding and its stated mission of promoting Catholic apologetics and giving correct Catholic teaching to random people who showed up with a question, wasn’t really set up as a place for individual Catholics to share their possibly dissenting views with the world.
One problem with this forum, and one reason why it’s going down in flames, is that the people who came here had all kinds of different ideas about what this forum was for and what should be okay/ not okay to post here. In the end it was trying to be all things to all men and satisfying very few people.
I’d note that if you just want to read stuff from Catholics who have dissenting views with the hierarchy, you could go on a very liberal forum (like the America magazine page) or a very conservative forum (like one of the SSPX/ sedevacantist forums) and read that all day long.
Edited to add, another reason for potential “reluctance” is that if a religious person knows he has some audience that is looking to play “Gotcha”, whether it’s unbelievers looking to draw negative conclusions about Catholicism, or fellow religious people seeking to “admonish”, then most prudent religious people are not going to say anything publicly. Religious belief struggles are often deeply personal and difficult, like marital struggles. Many people are reluctant to share them with folks who will use the info to jump to some conclusion about them, the spouse, or the marriage.
