Indeed! Both Jesus and Paul seemed to say that each Christian had a responsibility to not stumble someone else. It was not a matter of "Well, if you're weak and don't understand why it's okay for me to eat meat offered to a false god, that's your problem". You had to consider how your actions could affect someone else's faith, even if they were "weak".
Interestingly, JWs are strongly encouraged to follow this advice when it comes to letting themselves be trodden on in the name of forgiving and forgetting wrongs done to them by brothers, and when it means not watching/reading certain entertainment, but the organization itself doesn't seem to have to be concerned with how any of its actions (*cough*UN NGO*cough*) might stumble others.
