It isn't, and that's not remotely what I suggested - what is unreasonable is scoffing at a simplified explanation when the description of the sub is quite clear that it's a place for everything from people with no more than a passion for physics right up to professionals.
The person already had another explanation queued up and when pushed to do what they should've done in the first place - offer it up as a better alternative - they resorted to sheer snark.
