I'd just like to reiterate that his premise is just wrong, unless he is talking about his freedom as an ethnically English man in what was then a super-power global empire. The governments in so-called liberal democracies in the first half of the 20th century were literally sterilizing substantial proportions of their populations for a variety of non-violent existential reasons. Again, Turing is a prominent example.
No infringement of freedoms today by the same liberal democracies is anywhere close to that.
I could see an argument that maybe much of the west declined in freedom since the 1970-1990s, but before then? Really?
Anyway, looking up his views he seems to be an old school center-right conservative who is probably disappointed that Britain voluntarily gave up its empire more or less. Probably doesn't see the far-right favorably, but also likely thinks the left is worse.
