Invoking Article 50 was a separate issue from the referendum vote, which was advisory, lest we forget. Had it not been a separate issue, there would have been no need for a parliamentary vote on it. As it happens, I was not disenfranchised by the fact that no major party opposed Article 50, any more than you were disenfranchised by the fact that no major party was in favour of leaving the EU. There is no rule in parliamentary democracy that states that both sides of an issue must be represented in Parliament. No major party now opposes abortion or is pro-hanging or pro-foxhunting with dogs. No major party wants homosexuality to be illegal. No major party is opposed to gay marriage. Millions of people in this country disagree with each of those consensuses. They are not disenfranchised. They merely live in a parliamentary democracy in which some things are inevitably disagreeable to some people. Lots of people even. You can't just cherrypick your own bee-in-bonnet issue to moan that you were disenfranchised over it and ignore the other issues just because it suits your supposed case.
