Hi Cofty,
I wouldn't say "just as valid and worthy" as I wouldn't even say all objections arising from disabilities are "just as valid and worthy" as all others. The reasonable accommodation test will determine if the request is "valid" or "worthy", which is a much broader subject. I have a much higher standard for undue burden for requests which arise from personal choice than from those that don't.
But, that isn't the goal post here, we aren't arguing about degrees of tolerance or the application of tests for reasonableness in different scenarios. Arguments from extremes are an unnecessary distraction. The disagreement is about whether reasonable accommodation should happen at all for personal religious objections to carrying out aspects of a job.
If I understand you correctly, you have said that people should keep their religion / superstitions / personal views at home and do their job. I have been asserting that religious (and ethical/moral) objections to carrying out aspects of a job are worthy of reasonable accommodation, as are disabilities.
Simply put, I don't want to live in a society where, for example, doctor's who have sincerely held objections to euthanasia or forced sterilization (insert current medical ethical debate here) will be fired if they don't conform to the current political or moral consensus. Therefore, I can't support the idea that people should leave their personal views at home and just do their jobs. After all, one day it could be my sincerely held personal view that is at odds with current consensus, and I don't want to be fired if I can propose a reasonable accommodation that causes no undue burden.
