Anti Western folks literally believe that Afghanistan was more illegal than Iraq. You aren't going to convince them otherwise. It's very similar logic and evidence that the folks that claim we should've invaded Saudi Arabia instead. It largely discounts a lot of the western narrative as false simply because of who it came from.
A bit off topic, but how many dislikes do you see, and what app are you using, or are you using the website? I couldn't see any downvotes on kbin, or in jerboa when you posted.
Those appeared later. I'd like to learn more about how kbin/Lemmy work. It is possible that the dislike came from their instance, and it just took some time for kbin to update it, or possibly there are some dislikes from other instances that we can't see here.
