You're right of course disagreement should be explained better.

But he is responding to a one-line meme whose only purpose is to establish learned helplessness and end discussion that massively oversimplifies a very complex issue and is essentially copy pasted in any article here that even touches on politics. It gets quite exhausting engaging, having long in depth discussion about how this view is overly simplistic on every single thread only to have it appear again tomorrow, exactly the same as before.

I think downvotes and silence is the correct move here.
