Except I honestly don't think these answers weren't meant to be sarcastic. I sometimes skim through Guardian comments and these seem par for the course.
I've lived in the UK for way too long now, so my sarcasm detector is finely tuned... and I do think those are satyrical comments. It'd be hard for a clueless idiot to hit these buttons quite so precisely. Must be some smart commenters on the Guardian website!
