I understand why they want to, but professionals give and have, consent. This is just kink shaming, honestly.
There's already done fairly aggressive agree verification laws there that were recently enacted, if memory serves me correctly, so now you're telling agree verified adults what they can, or cannot, watch.
I have zero doubt that the actors in the adult films depicting these kinds of scenarios are consenting adults. And while it may not be everyone's kink, it is some people's. If you don't like it, don't watch it. You're an adult. Deal with it.
Making laws so that everyone needs to abide by what you think is acceptable in terms of sexually explicit material, is ridiculous, with the only caveat being that all people involved must be consenting adults (depictions of non-adults is another legal matter entirely, and should continue to not be permitted - this is one of the few exceptions to the rule).
