> subjectively problematic

I might recommend using a word more specific than "problematic" if your goal is to communicate your criticism. It's about as specific as "bad", and seems to form an in-group out-group dynamic for readers who get to fill in the gaps.

I agree with your point, so I've read your comment as "it makes your reply more biased than necessary", whereas people who disagree with you might read it as "I don't like your reply because it hurts my feelings" or some other uncharitable interpretation.

Hope this came across as a friendly recommendation! Communicating over text has so many pitfalls.
