Ok, on one hand his parents are abject cucks with no real beliefs or values beyond doing what the electric jew tells them. Their son is right to reject their dying world in favour of something with a bit of fire in it. On the other hand, while they haven't exactly earned his respect, he should still be treating them with at least the same amount of respect he'd treat a housemate. Going full zealot on your own family is not good. Neither is searching through their private posessions.
