True about dogs and s--t POGS as they are, unfortunately in one case, physical things.
However, it is Annie's opinion of someone she doesn't actually know and she has characterised the character "Corbyn" as a liar and a hypocrite, so this is her Corbyn, a made up character and not the real living, breathing and as complex as the rest of us Corbyn.
I believe therefore, and would be interested if someone with more knowledge than either of us could tell me more, that as "Corbyn" to Annie is just a character she defines by the characteristics she hates, the simple logic still works.
Logic can be very fascinating.
