The Tories only care about fptp or are illogical

If we assume that all Tories support fptp (and that seems a fair assumption) then we can deduce that the Tories are an illogical party and that it is illogical to support the Tories. The reasoning is as follows: i) First past the post is very good for Labour... if people don't like the Tories for whatever reason (and there are many) then it is natural that voters will give their vote to the Labour party. ii) Something which is good for the Labour party is (presumably) not good for the Tories and not good for the issues which the Tories are interested in. If fptp is the only reason the Tories are supported then there is a certain logic in that but if Tories care about anything other then preserving fptp (such as anti-socialism) then fptp is bad for them and their policies. Tories are only about preserving the antiquated fptp voting system.
