This might be worth exploring.
How far are you taking this? Are you just talking about porn itself or sex in general? Are you suggesting that anyone who takes a moral stance regarding sex is doing so because of a religious root? (I assume, based on the posts of yours that I have read, that such a root is in your opinion a thoroughly irrational one.)
The only "moral stances" on any kind of sex or sexual subject have always been religiously motivated. It's only the religions that have a problem with sex, and then only some religions. I can assure you, as long as the sex is legal and consensual, the atheists I know have
no problem with any kind of sexual subject. At worst they are "well I'm not really into that, but you do you". It's only
religious people who say "you shouldn't be doing that because it's
bad".
It's not an irrational opinion, it's one formed from experience. Moralising is a religious undertaking,
especially where sex is concerned. It's only the religious who have problems with homosexuality or sex outside marriage, or with multiple partners. It's only the religious (and those who listen to them) who have problems with legal, regulated prostitution, and it's only the religious (and those who listen to them) who have problems with legal, regulated porn.
Don't neglect to read the important part there:
legal and regulated. I certainly do have major problems with sex trafficking, forced prostitution, and nonconsensual and underage sexual activity. If you dare misrepresent me on that I will come down on you like a ton of bricks. Metaphorical bricks, delivered over the internet. I guess.
You previously defended porn of this type - you focused on the fact that the actors are all of legal age - all over 18s whilst ignoring any other considerations. And that is why I posted that documentary - it features (blurred) footage so that we know what we are talking about (in terms of age optics).
There are no other considerations! What other considerations could there possibly be? I know for a fact that the actors are of legal age and are consenting to performing. They are being paid for their work. Why should I give a ◊◊◊◊ about anything else?
You are aware, of course, that just because someone is wearing a schoolgirl outfit does not mean that they are underage, look underage, or can be mistaken for being underage, right? Particularly the kind of hypersexualised "schoolgirl" outfits that tend to feature in porn?
Oh, you don't think those are
real schoolgirl outfits, do you?
Also, let me introduce you to Japan. Careful, your head might explode. Japan is
weird, even for me.
