Sparkly: Why do you say that? Why would it be apikorsus?
DY: Laws, for instance. Or a historical account of something horrific that happened. It depends on the context. One might “struggle to accept” the fact that Dovid HaMelech’s ancestors were alone on a bed together at night before having been married, for instance. And in fact, all the meforshim on this subject clearly do struggle with it. You can substitute different words, though, if that makes you feel better.
lilmod ulelamaid: Isn’t it better to keep some mitzvos than no mitzvos? Don’t you think a person who keeps something is more likely to someday become frum than a person who keeps nothing? Do you realize that not all people who call themselves Conservative or Reform actually identify with the ideals of those movements, i.e. apikorsus?
