I'm sure some people are, but the idea that the only way you can derive ideas like "human life has worth" is from religion feels like a huge step backwards.
It's actually not the only topic on which I think it'd be a lot easier to work as a conservative operative or pundit crafting or delivering arguments against what I believe, than as a liberal operative doing the same in favor of what I believe. I'm not sure if that's true for a lot of people regardless of their beliefs—that is, that it's just way easier to argue something you don't actually believe, in general, so there are also some conservatives on the other side going "man, it'd be so much easier to argue for liberal positions"—or something about the level of nuance or whatever required to vigorously defend current liberal positions versus the difficulty of defending current conservative positions. Hard to judge which is the case, for me at least.
