Saying Muslims that wear burqas look like "letter boxes" and "bank robbers". I expect more from the leaders of our nation. Don't you? Or is this where the bar is now?
Do you honestly think somebody wearing a burqa is somehow going to change their mind after reading that? Are they really going to think "Oh shit! OMG, I look like a letter box. LMAO, thanks Boris!". No, it's going to make the issue worse, because it'll piss off a proportion of the Muslim community and inflame the ignorant/intolerant/racist.
I didn't say there was anything funny about it; although it's clear he tried to inject some humour into it with those remarks.
Who's trying to shut the conversation down?
