That may be true, but up to now they've not had much luck. I mean, again, let me remind you: Theresa May signed Notification under Article 50; she need not have; and Theresa May introduced and insisted on Brexit Day being specified as March 29, 2019; she need not have. Those aren't inconsequential. Remainers were screaming for neither of these things to happen, and she did them anyway. It's also not at all irrelevant that there have been at most five victories for Remainers in the Commons, and all of those were minor. Everything major Brexit-related has gone through unamended.
I mean, I'm sorry, but it really is nonsensical, because it ignores recent history. If I had been a Remainer truly trying to thwart the will of the people I'd like to think I'd be doing a much better job of it than this crap.
