Libertarians can't exclude the right because of fptp

The problem with fptp is that it (almost always) leaves us with only two parties to choose from. If we assume one of those parties will of the centre-right and the other of the centre-left then it is natural to expect that a libertarian would prefer the party of the centre-right... which we will call the Tories. However a problem arises when the Tory party supports some policies which are offensive to libertarians. Then a libertarian has no realistic choice. Under pr such a voter could just switch to one of many liberal parties and still have their vote be affective. Fptp makes it impossible for their (libertarian) vote to count and (at the same time) not to support some egregious right-wing views. With fptp we (as libertarians) are given a choice between voting for some offensive right-wing views and not voting at all... which is not to have been given a realistic choice. It is impossible (as a voter) to exclude the nasty right-wing views and still vote a for a party which is of the right. Fptp makes it difficult for libertarians to exclude the right.
