To vote in a first past the post election is not logical

Democracy is good because if the government is good (for the people) it will be popular and elections will present no threat to the government. Elections are a threat only if the government is bad for the people which means that democracy is only ever a positive thing. There is no reason to oppress democracy and yet to not have proportional representation and to instead have first-past-the-post is to oppress democracy at least slightly. Very few people interested in the subject refute that pr is more democratic than fptp... adherents of fptp generally accept that it is less democratic but suggest that in some sense democracy is not entirely to be welcomed.

There is no reason to suppress democracy so there is no reason to have first-past-the-post over pr so a government which is using fptp is knowingly suppressing the people which is both evil and illogical.

When faced with an act of evil perpetrated against ourselves then it makes no sense to comply with this process. To vote in a fptp election is to consent to the system and to be complicit which is not logical since evil is not logical.

There is no rational reason to vote in a fptp election since the system being used is wrong.
