Porn isn't wrong in and of itself. There's nothing wrong with consenting adults engaging in porn or watching porn.
The problem is, is often IS exploitative. We need to have honest and straightforward discussions about how to ensure that those engaging in porn ARE consenting adults.
We also need to be educating kids about porn so that they're growing up with healthy attitudes about sex, consent, boundaries and intimacy.
We also need to be sure that those who make porn are fairly paid for their work. The rise of free porn sites has massively disenfranchised those who star in porn (usually women). Free porn sites are also not doing enough to ensure they're only hosting videos where all participants are consenting adults.
Basically - porn is fine, adults can do what they like. But it should be regulated to protect participants, fairly paid, and a topic kids are properly educated about.
