To answer the actual thread: I wouldn't say "smaller state" is necessarily a Tory "value". Definitely it's a strong wing within the party but it's by far not the only one, and it's hard to argue that the last few years of Conservative rule have been particularly small-state libertarian...!
Words/phrases/values like: doing your bit, service, quiet patriotism, for King and country, mustn't grumble, knowing the neighbours, charity begins at home, British sense of humour, pints at my local.
^ none of those things are party-political but in some ways they are more associated with the Conservative Party, because they more explicitly claim to value them and tie them to a concept of British culture which they want to uphold.
Those values go deeper than economic policy preferences and if they are attacked, it causes a stronger reaction.
Currently, the Labour party has a highly-visible activist wing which is quick to label any expression of patriotism or pride in Britain (heck - even using the word "Britain") "nationalist", loves corporate trainings which say that drinks after work aren't inclusive and Little Britain is problematic, demands highly-personalised treatment for every niche identity... Is it really a surprise that Labour are struggling to attract voters despite the poor performance by the Tories?
