Nom, we’re prohibited from exposing ourselves to negative influences, including hearing apikorsus, no matter how “strong” we think we are. It’s a clear violation of halacha to read or listen to apikorsus, unless one is on a very high madrega and is doing so to refute it.
Same with toeva culture; the rambams statements about influence are yaduah, and it’s just arrogant to say that one should just be strong; such people are usually the most influenced, but they’re unaware of it.
