(The Tory position on) fptp is a bit like terrorism

The method by which the Tories gain tactical support is to explain that the Labour party are much worse (and less liberal) than the Tories and so voters should be fearful of this outcome and vote for them. This is very much like terrorism in that the voter is being coerced into doing something they would otherwise not do out of a fear of physical force. The Tories are using the threat of a Labour victory to coerce voters into supporting them... which is very much like terrorism. The Tories are relying on voters being sufficiently fearful of a Labour victory that they will vote for the Tories out of fear. If the voters are not scared and not cowards (who vote tactically for the Tories) then this tactic will not work for the Tories. The Tories rely on voters not being brave enough to tolerate a Labour victory (assuming they are disposed not to support Labour). The Tories rely on non-Labour voters being sufficiently fearful of a Labour victory that they are prepared to vote tactically for the Tories when they would not otherwise do so. The tactical votes received by the Tories are gained through fear of a Labour victory.
