Maybe you are right, on ignoring a study weaknesses and red flags is bad scientific practice.
Is that I have been involved personally so long in this topic, that I know for a fact that the results are Good. As I also know many good studies being ridiculed and buried on purpose. No one in the scientific community would dare to criticize a paper in that way. Constructive criticism is connected to intellectual, educated minds, all the rest deserves the same coin or being ignored.
I still don“t understand why that comment on top, (I have seen this to many times).
