The post does point out that there’s a table full of penis models (so essentially dildos) and that the task is to put a condom on one of them.

A bodyless fake penis is clearly not a sentient being so the only way a violation of consent happened if consent applied to inanimate objects. That is, of course, a ridiculous and easily attacked proposition.

In the end this would be an example of trying to make a valid point but making it in a clumsy way.
