To the DPS META and please be reasonable with arguments

[Taika]

You're wrong, you can't retaliate a healer for not dpsing. And I will say more, if you do that you can be punished by a GM for harassment.

You can kick people for different playstyles, and this definitely falls under that.

But I won't automatically kick a healer who doesn't DPS. I will ask them nicely to participate with DPS when no one needs healing. Then if they refuse without any reason than "lol no that's not my job", I will initiate the kick (although even then I will probably first try to explain why it is their job and why it is so useful for the whole group). And I would do the same with a BRD who refuses to sing or refresh TP/MP because they're called DPS. :P

(Edit addition: If they say they really can't right at the moment because of being super nervous or having a massive headache and just trying to get through the instance or whatever, that's fine. What I can't stand is not trying to put some effort and intentionally making the rest of your party work much harder than you are.)
