Grammatically I also prefer
People on blonde are never pedantic.
to
Pedantic on blonde, never. (note the full stop)
but that's pedant semantics for you.
Of course, you're right. I should have changed it to:
Pendantic on blonde, never? or even
Pedantic on blonde? Never!As his sentence was obviously a question, even if it was rhetorical. I am now going to give myself 100 lashes as punishment for my error. That'll learn me.
