Fantastic article Steven, this is actually something I've spent a considerable amount of time trying to wrap my head around recently.
Namely, is it worth chiming in and attempting to combat Umair's divisive articles, which I'd argue are quite harmful in their fear-mongering, when in doing so you're perpetuating this type of click-bait.
Like the other commenters, I was really enamoured with his articles when I first joined medium but it very quickly wore thin; the world has enough negativity to spend time reveling in his style of writing.
So I muted him - but that doesn't feel very free speech to me, it feels quite defeatist to do so.
I suppose the easiest thing to do is label it 'click-bait' and move on, but I fear with the new Medium update these kinds of echo-chambers are only going to grow in popularity.
