Your comment reads like you're questioning their right to have an opinion based on demonstrating their qualifications to your satisfaction. That, and they have to reveal their identity on the internet to satisfy your requirements. I don't know if it was clear to you that that's how it sounds.
I see two possible readings of your comment:
1) (less generous) a veiled suggestion that the OP should only have such strong opinions if they match your bar for expertise
2) (more generous) an off-topic question about OPs work
Both are worth a downvote imo.

Sorry but, what?
This is just nonsense.
is that not similar to your critique of the author
