A nice response, as it works almost perfectly regardless of which side you're on. (All except for the word "nationalist," it gets in the way.)
UPDATE: Some readers seem to be reading my tweet as implying a series of unstated arguments that they find profoundly wrong, so let me be clear that this tweet is not intended to imply any unstated arguments. /1
In particular, some seem to think that by noting that there are two sides with structurally similar views, I must also be claiming that both are equally justified and there is a moral equivalence between them. Read my twitter feed; I don't think that. /2
On the bright side, "This is shameful drivel" would be a pretty cool motto for my Twitter feed. /3
