When I say believe, I’m borrowing the term from the thread title. I think it’s not something we would normally categorize as belief.
I think one is only entitled to an opinion if it’s Talmud based, as you say, but it needs to be from the same perspective as one should have on any sugya: you can come out understanding one tzad better than another, but with the recognition that we’re ants compared to the Rishonim, and that our opinions are severely handicapped by our limited mental and spiritual abilities.
