Only proportional states are valid

Contrary to the claims of its adherents first-past-the-post does not give strong government. It gives weak government. Governments formed with fptp do not have a proper mandate which means they do not have the legitimate support of the people and are invalid. Only with pr can it be said that the state has the consent and support of the people. The state acts with no authority if its only mandate is a fptp election which means that fptp governments are weak. Governments formed by pr are strong in comparison to those formed under fptp.
