As for Jeremy Corbyn's quote, it's just that - a quote. It's not a quote that's been distorted or where one word's been taken out of context, it's what he actually said.
Here's another quote taken from his own website:
"Thank you to the Foreign Secretary for giving way. On the subject of refugees, he’s obviously as aware as everyone else is of the massive flow of migrants across the Mediterranean, many of whom thousands have already died also those in the Andaman Sea and elsewhere. There is a global phenomenon of victims of war, poverty and oppression fleeing in desperate circumstances. Does the government have a strategy of supporting refugees, of supporting saving life at sea, rather than repelling people seeking a place of safety?"
So why is Accyexplorer a "do-gooder PC lefty liberal" for saying similar things, yet Jeremy Corbyn isn't?
