I can see the need for things like parental filters, or better user controls to be able to get recommendations for things you actually want to see.
I would also be the first person to agree that Netflix has the right to decide what content they want to distribute.
But from a customer point of view what I want from Netflix is to give give me maximum choice. Give me absolutely every kind of content imaginable, offensive or G-rated, and then give me the tools to be able to limit what my children can view and to fine tune the sorts of recommendations I get.
I'm a huge believer in "if you don't like it, watch something else" and "if someone else likes it, that's none of your business."
The proportion of people not watching a show will always be far higher than those watching it, so there's room for offense from non-watchers to drive product decisions. The parent comment is saying that he doesn't want that to factor in at all, which is orthogonal to the question of Netflix needing to allocate resources between content.
