You have associated the highlighted parts. They are meant to be understood separately. The ones who have the qualifications in their
respective fields ought to be listened to, considering they have studied their specific field and hence have more knowledge then those who haven't.
The other part about critical analysis, could be interpret as a general thumb rule in life in general when one wants to learn more. You therefore go
to legitimate sources for a better understanding, rather then lets say an average individual with an unsubstantiated opinion. You have understood those two statements as associative, which is not how they should be interpret. Your argument is therefore invalid, since the premise of it is that you associated two sentences together which were not meant to be understood together. You listen to expert(s), and you use critical analysis when you want to study a certain subject, by differentiating legitimate and illegitimate sources.
I'd propose that the overwhelming majority of the posters on this thread don't have a 'medical qualification', does that mean they are not entitled to have an opinion? Sure, when statements are made that go against consensus within the scientific fields, that ought to be corrected which is the rational thing to do.
I also respectfully disagree with the statement of lacking the basic tools to understand the topic discussed. I've cited legitimate sources on this thread linking to the WHO and other studies to provide another perspective, not as an generally accepted consensus in regards to that specific subject. It would also highly arrogant of one person to say that they are fully equipped to understood the ins and outs of this broad topic of Covid. Hence, the tool to cite sources and to interact with fellow posters to get a better understanding through dialogue. I've also emphasized that vaccination is vital to get this pandemic under control, which is a consensus and accepted in general. I therefore fail to see where i haven't understood 'the basics.
The other subject discussed was in regards to natural immunity and legitimate and i've cited sources to substantiate that claim, without proposing that conclusion as an absolute truth, that would be unscientific. Don't take this personally, but in my discussions so far it couldnt be more obvious at that you at many points haven't understood the essence of my argument. That doesn't mean your slow, stupid, or poorly educated! (little bit of banter).
Nonetheless, life is about being better not bitter. Having an open mind and the willingness to learn should be a requirement of any open, rational and
logical conversation!
You do have to forgive my on me english at times, it isnt my first language
