I'm not missing the point where payment processor aren't police. But they still need to follow legislation in the region they operate.
First of, it's not "Point in case", it's "Case in point".
Second, I can honestly say. I have no idea how many payment processors does or does not authorize payments regarding legal porn for various websites. Feel free to link an article or source that investigates that particular topic.
If you look at the post. They claim "Possibly related to PayPal because people in certain regions have not been able to use it to pay on Steam."
If this was PayPal taking a stand on a corporate level against porn games on steam. Why would only certain regions be affected instead of everyone?
The obvious answer, is that it's only certain regions, because of their legislation. If PayPal wish to do business in their region. They have to follow their laws for those customers.
There is a big difference between guns and guns. I don't know where you are from, but are you sure that you are not even allowed to own a hunting rifle for hunting?
I wouldn't say I have a strong opinion on guns. I suppose that might be subjective but I don't consider myself a gun-nut or anything. If you're just curious, the answer is deer and wild hog, but mostly wild hog. For one they're invasive, and secondly, I think they taste really good, so win, win. But it's a lot of work, not the shooting part, but afterwards to take care of the meat and all. You need to send it in for testing as they could have parasites that are dangerous to humans (even when cooked). I would like to hunt moose at some point but I'm not really in any rush, it's also highly regulated.
As my opinion on guns, I think they should be allowed where it's reasonable, provided the person have a valid weapon license. I see no reason for full or semi-automatic rifles in civilian hands. I'm pretty sure some semi-automatic rifles are legal. But I disagree with it. And it's possible they will ban them soon. I know it's possible to get license for pistols. But it's very rare. You are not allowed to have them for self defense.
