He is not a pilot - yet argues with the most experienced of them.

I'm worried that you may give the wrong impression of what the issue is with
this particular contributor, possibly discouraging legitimate participants
from posting here. There's nothing inherently wrong with someone arguing

I don't see why there'd be anything inherently wrong with that, either. (And
he does in fact participate in other threads.)
