Presuming this is the case, then I don't see the point of making it about religion if sexism is universal to all humans and all human institutions.
If you're assuming that religions are all human institutions, then that makes sense. However, many people - i.e. many of the adherents of revealed religions - believe as a point of faith that their religions are *not* human institutions.
I think there are also different ideas about what "religion" means. I get the sense that the OP is talking about sexism in the "official" teachings and beliefs of a religion, distinct from the personal views of its members and I've been approaching the thread on that basis... i.e. making a distinction between sexist beliefs of an individual member of a church and sexist teachings of the church itself.I'm skeptical that 100% sexism free is what the OP was going for, given the impossible standard that represents. It'd be a rhetorical or trollish POE of an OP were that the case. It seems you and other contributors to this thread have very different ideas regarding what this thread is about.
