Like I said... if you don't do anything silly. All the things you describe are silly.
I'm a 146 line trainer, and quite frankly one of the tools of the trade is being sure of your ground, and standing it whenever you have to. There are ways of ensuring your career doesn't suffer - keeping good records is one of them.
There is no way you can end up with a problem if you refuse to land below minima - all the facts are on your side. In fact, if you do, it is likely that both you and the company will be in the crap.
If your Ops Manual allows you to release a guy to the line under the conditions you describe - and most don't - just pass it on to the Chief Pilot. I have failed quite a few in my time, as long as your reasons are sound (and the paperwork reflects that), you are fine.
It may be as bad as you describe, I don't know, but there are ways to protect yourself.
So I guess you are saying I shouldn't apply then...???
