I think we are stretching the definition of a meme here. This was original content orchestrating attacks. Not some repost of a joke (however bad taste it might be).
At which point is the boundary between meme and instigator?
I'm pretty sure that's the point they're getting at - that the original person commenting was talking about this stuff like it's just memes, in bad faith.
