I think being a life-long supporter of anything shows ignorace and bigotry.
I generally have conservative views but have voted for Labour and Conservative in the past, been a member of of the Conservative party but voted Lib Dem years ago too.
Labour have changed and are no longer a party for the working class and trying to benefit all. They're now for wealthy people to signal their virtue and preach to those 'turkeys voting for Christmas' how ignorant and stupid they are to be both poor and voting for the Tories.
I think the only bearing that the EU had in this was thinking who you'd like to be going in to secure the best deal for the UK. I'll give you a clue - it isn't the man who sits on the floor of a train and forgets about mobile phones having cameras.
The main reason for Tory success is that May is a competent leader and we need one to steer us through a recovering (from Labour) economy, revitalising the NHS and making tough decisions as opposed to offering extra bank holidays!
I'm sure there are some people who would even vote Tory to stick their fingers up at the smug hand-wringers who think anyone other than their left-of-centre politics must simply be ignorant and uninformed. In the EU referendum I voted to stay but when walking to vote I was still undecided. The incredibly annoying social justice warriors outside the polling station nearly made me vote leave, just for the pleasure of telling them afterwards. I voted to remain but told them I'd voted the other way anyway. The best of both worlds.
tl;dr
stop the hand-wringing. Phrases like 'turkey's voting for Christmas' and 'pull the trigger on their own head' just show your ignorance and inability to broaden your mind beyond your own narrow set of political beliefs.
