I found it interesting that on HN, without concrete evidence, when OP says: don't ever trust {A} on issue {B}. Depending on what A, B is, OP will usually get treated differently.

A -> CCP. OP -> a concerned citizen.

A -> Race/Color/Religion/Gender. OP -> Racist/Sexist.

A -> Trump. OP -> a concern citizen.

A -> Scientist. OP -> conspiracist.

But one thing that I am sure is that it'll never ever be constructive. Not mean to be disrespectful, but I do hope this type of comment won't ever get to the top of HN.
