I'm pretty confident some of it is not legitimate Islamophobia and is a reddit wing of a broader social media campaign on behalf of the genocidal settler state. The campaign is more visually obvious on twitter to me; I think the surface anonymity of reddit makes it harder to see at a glance. But you can notice, for example, how mundane subreddit names get used to launder posts that are obviously targeted propaganda against a particular group. The most transparent being r/pics, but a less obvious one I've seen is the subreddit r/UnbelievableStuff

That's not to say there aren't real Islamophobes on the internet. Just that it being worse is almost certainly manufactured, to some degree.

One instance in particular, I don't want to go into detail on it here in case the details could indirectly link my reddit account to here (I'd prefer to keep them separate) but suffice it to say, I have reason to believe the person's Islamophobia spewing account is not a random reddit user who just happens to feel that way.
