A disgusting individual from a disgusting party. Even by Tory standards, that is an absolutely despicable, deranged thing to say.
Understandably, everyone is comparing this to Swift's Modest Proposal, but if anything, I think this sort of thing proves we're almost completely beyond the realm of satire now. Swift's satires were often executed by saying something incredibly shocking that would prove the opposite point (for those who aren't familiar, in A Modest Proposal, he argues that as a solution to hunger and poverty in Ireland, Irish children should be sold as food). Now, it's the politicians who say the incredibly shocking things, and they are far too stupid to do it with the ironic intent of Swift. Swift wrote A Modest Proposal to expose the callousness of the English ruling classes; the likes of Patel only expose their own cruelty and ignorance.
