The problem with this analogy is that the dog shit in this scenario is between you and your destination. The dog shit IS the destination when it comes to content some would find objectionable. It's not a matter of being unable to avoid the shit, it's goomba stomping a pile of shit and then crying impotently on the internet that you got exactly what you came here for.

Take r/watchpeopledie, for instance. You know damn well what the content is from the name alone. It had a big neon yellow warning that it was for adults only due to the shocking and disturbing subject matter. People still complained, not because they were stepping in shit, but because they were seeking out shit and rubbing it on their faces to make a (stupid) point.
