Any media consumption isn't bad praxis, its just not praxis. ML theory says nothing about media consumption, and it does literally nothing to further our goals.
Like, praxis is just putting theory into practice. Obviously not everything in a persons life has to relate to theory, not doing praxis is nothing like a sin.
Bad praxis is more like trying and failing (like right action, wrong material conditions), or being counter-productive. Whether its actually a problem or sin equivalent is entirely context dependent, plenty of people who did bad praxis are hailed as martyrs.
