No,but rephrasing the man of straw doesn't help.
Let's say there was a vote to censure the Tory govt and the DUP voted against that. Are you honestly saying that that would in no sense be support of the PM?
Poor analogy - this vote was in the European Parliament, not in the commons. There will be plenty of examples where Tory members have voted in manners we might find unacceptable (e.g. in Local councils, Welsh/London/Scottish Assembly/Parliament or in the European Parliament. That doesn't mean that May supports that action, let alone support any particular individual who might benefit.
I imagine up and down the country there are examples of Tory councillors voting in support of Labour administrations on certain topics - does that mean (as you seem to be implying) that May supports Corbyn. No it doesn't. It doesn't even mean that May supports Harry Smith, the Labour leader of Bloggshire Council if he has received the support of Tory councillors in a vote.
