Others here have provided reasons why Tailwind is great, and many comments just center around how it's at least not a bad idea.
But for myself, I read a lot of these arguments before and wasn't convinced until I used it in a fairly big project. To some extent it's hard to explain the benefits because once you get past the more 'ideological' issues (separation of concerns, etc.), it's really much more about how it affects the flow of day to day work. I don't think any arguments would've really convinced me, but because of the excitement around here I gave it a shot, and was convinced by seeing how my project grew without many of the usual CSS issues I'd run into (as well as the convenience of just not having to switch to a stylesheet file most of the time).
But I do understand how frustrating a comment like that can be.
If you don't want to do that then you could watch some of Adam Wathan's screencasts on YouTube where he uses Tailwind to recreate pages or build new ones.

This smells a lot like every other tech bandwagon. It's the best thing since sliced bread until wide adoption exposes all the flaws and we go back to what proceeded it.
Something seems fundamentally off about this library, but I can't pinpoint what.
I waited a while before bothering with React, but based on my positive experience with that particular 'paradigm shift' I gave Tailwind a shot. So far it's been really, really pleasant on a moderately-sized project, so that's hopeful.
I don't see the point in dismissing it, based on all that. We didn't go back from React to jQuery and Backbone, we moved forward from it.
That said, it's fair enough and probably smart to wait and see at this point if you don't have the luxury of experimenting. I totally get that.
