"Mercy" is for a group that concedes that they may one day lose and so shows grace that they may themselves receive it in the future.
This group does not anticipate leaving any survivors from it's opponents to remember whether they had any grace or not in the first place.
Of course they are.
Just from their name, they believe that to fail is to see the end of humanity.
If they genuinely believe that, what atrocities would be out of bounds? None at all - these people think they're playing for all the marbles.
Well, given Sir Kier Starmer's comments (I always add the "Sir" when I can, because he likes to pretend he's a man of the people), they're more likely to abandon Labour and go hard-line Muslim third-party than they are to vote Tory, it seems.
Just think, Britain could soon have it's own Hamas party!
It's actually something of a step up that this one even concedes misandry is a thing in the first place.
