1) assumes that all levels of 'cooperation' with what you perceive to be evil are equivalent. I happen to agree that both testing medication and using cell lines to develop it are more or less equally distal to the original problem (as it is perceived), but not all people do. (The distinctions between formal and material cooperation, and proximal and distal cooperation, are relevant to many ethical systems, even outside of religion.) 2) is irrelevant to people not in the camps of 'most religious leaders' or a 'major religion.' I mostly agree with you on 3). I think some positions are simply not open to some people with certain religious beliefs. A devout Muslim cannot work at a liquor store. An evangelical cannot be the JP anymore. An anti-COVID vaxxer (even for religious reasons) can't work for the federal government. So it goes. However, these considerations are only tangentially relevant to a consideration of the morality of a register on these exemptions.
