I'm not really getting tetchy, although it is frustrating that you can't seem to see the basic fallacy in your argument. And it certainly is legitimate to call it an effective Project Fear.
One thing worth adding, too, is that supposing for the sake of argument I was in abject poverty, then what exactly is your message? "You might be in dire straits now, but voting for Labour won't make things any better", presumably. But why would you expect anyone to not wish to at least try and take the chance? They're already in a horrible mess. Voting for someone who at least will try to address that, as opposed to the current lot who don't seem to wan to try, seems a worthwhile gamble.
I wonder how much you really listen, if you don't seem to understand this rather basic point. If, as you say, you can "afford" whatever abject future you fear under a Corbyn government, perhaps you aren't in the position to understand why it might be seen as worth the risk. Put another way, can you not see that the last Seven years of Tory rule (yes, even under the Coalition it was essentially mostly a Tory government, tempered only slightly) haven't exactly brought any real incentive to many to continue voting Tory?
It's not tetchiness to express some amount of... I don't know... confusion? Frustration? -- at how you don't really debate, so much as talk down to.
