His soul is at stake, not yours. I rather feel sorry for people getting things that wrong, because it means the Holy Spirit has not entered their hearts yet.
You're not an observer in life, you're an active participant. One does not simply watch something without any sort of participation in that act. Merely looking at a woman in lust is adultery, what then is choosing to watch someone who blasphemes? In watching him, his numbers go up, he gets gratification from that. He is more likely to continue. If his Christian viewers, the vast majority of his viewers, stopped watching him he'd say "oh I probably should stop blaspheming if I want to feed my family." Instead people come up with excuse after excuse, deflection after deflection, to justify feeding into a channel that continuously blasphemes without repentance. You do not care for Owen Benjamin's soul, not really, if you continue watching him after he blasphemes. There are so many better alternatives to watch that give similar analysis without blaspheming, there is no gun to your head forcing you to watch Owen Benjamin.
If he insulted your mother, your wife, your daughter, in the most vile terms, only the lowest worm of a man would continue watching that person and making justifications for other people watching him. It would be unbelievably pathetic. You cannot say you would watch him after that sort of an insult on your family. We cannot place our family above God.
The arguments for watching Owen Benjamin are no different than for watching pornography. You get pleasure from watching something wrong, and you claim observation is separate from the act, and/or that the blame lies in the actors, producers, those who host it, etc., or you claim you watch it for the plot. It doesn't matter if the most enlightening secular discourse in the world happens in the midst of a pornographic film, you still do not watch the porn.
