The legalities have been more than amply addressed here already and, in any event it's clear that the "senior pilots" don't see a problem with them. So I'll put that aspect to one side for the purpose of this post.
Those "senior pilots" might be more interested in the fact that each time they slip below the MDA, they're voiding the company's insurance policy! If the pilots aren't interested in that aspect, I'll bet the company will be.
