Honestly, you don't have access to the necessary data to make rational decisions. That's not gatekeeping, it's logic. I don't have access to it either, although I'm indeed a healthcare pro. Screening strategies are a hyperspecialized domain and only experts somewhat understand what they're doing. It's just like making theories about what the CERN guys should be doing while not having passed physics 101 with no access to experimental data. That's why I'm just saying: you're certainly allowed to question, but you certainly can't make up assertions either.
