I assume you're commenting on show 3445, which is a response to this show 3414.

You are of the opinion that common sense outweighs the knowledge achieved through the scientific method. History seems to disagree. The "common sense" prior to the discovery of "germs" resulted in the death of many who would have survived if hand-washing had been more common, for example.  There are huge numbers of similar examples.

You make an assertion about masks, which I disagree with. You assert that your view outweighs the research we cited in show 3445 yet your only support for this is that you state it. This seems typical of the current trend to put forward opinion as superior to fact.

You mistake trust in the scientific method and the results that this method produces, in comparison to those who misrepresent this method and these results for their own agendas and profits. Agreed that many politicians, industrialists and even some dishonest scientists are known to do this. However, where human beings may sometimes be unreliable the properly conducted and peer reviewed scientific method is not.
