I find it interesting how writing "a male" instead of man is a good way of pointing out "sexist mansplaining" and writing "a female" is dehumanizing (which i actually agree on). I will not deny that there are many sexists out there who are mansplaining or see women as less knowledgable. Without knowing the person ("offending") however, i think we would be wise to use occam's razor which would lead us to the conclusion that this is a prime case of the dunning kruger effect (which would also apply if sexism is involved).

Mycomment however has to be seen as mansplaining because i sadly have a dick between my legs. Sorry for that.
