Replace porn with water and you can easily see why this is a bad take:

You: Water is bad and should be banned. It causes [bad thing].

Me: You’re saying that a lot, have a source?

You: Google “harm from water.”

In reality, all that search shows is that porn can cause harm. And no one is going to be surprised by that fact, it’s a well known issue. You know what else causes harm when misused? Any prescription medication, anything you buy from a grocery store, literal rain. Pick something, and I can show you how it can cause harm.

But what I asked for, is a source to your “porn causes incels” claim. If you don’t want to provide a source, that’s fine. Just be aware that you’re immediately going to be mocked with comments such as:

Your source is that you made it the fuck up.

Holy loaded (pun intended) search phrase, Batman! 🤦
