Perhaps your comment is a bit of a rant with highs and lows, but this is a rather powerful analogy.
Growing up in Spain, a country with a very strong Catholic tradition, I hated the Church and its invasive prescriptions. Still to this day I count my lucky stars not having spent my younger years during the Franco dictatorship, where being Spanish was inseparable from being Catholic by law, or worse yet, during the Inquisition where by law you could end up in burnt alive in a public square.
Now, however, it's mostly Progressives who assume this role of telling people what to do. This includes companies of dubious moral standing (Google, Uber, and others) who are constantly reminding us of what's Good, mostly for marketing reasons.
I can't stand it now, as I couldn't back in the day with conservative Catholics. Can't everyone just fuck off and stop preaching their shitty gospel?
I'm sure that in the depth of their hearts the coal miners not only understood but also accepted Thatcher as a fundamental and important part of society.
For example, say you suggested "God does not exist" to a Christian. More often than not you'll receive an emotional response: "You're going to hell, is that what you want?!", "So life is meaningless to you?", "I feel sorry for you", etc.
Say you suggested to a "Progressive Activist", something as objective as "You should defend the right to display the Confederate flag (while condemning the action itself)". Progressive Activists become irrevocably distracted by the emotional injustice that the Confederate flag represents to them. Responses often include: "No, those people are pieces of shit, fuck them", "Racists", "They're what's wrong with this country", etc.
The emotional disposition of Christians and "Progressive Activists" are nearly identical.
The purges will come soon enough.
> No conservative in the 1970s would have thought, everyone in Britain should be a conservative
Like the points your making. I would add that by the standards of the early 20th century when progressivism started even a 1970s conservative is a progressive.
Even taking American conservatives, who are more conservative that than their British peers, conservatives are fine with social security, medicare/medicade (NHS), and fine with government run education, and fine with an unbacked U.S. dollar funding this modern welfare state. I.E. even American conservatives are mostly fine with the lasting policies of FDR; perhaps our most progressive president.
What am I getting at?
My broader point is that Progressivism is indeed the current state religion. Both parties are 'progressive' parties by historical standards. The only recent development is that we are now approaching near total domination of the cultural, political, and legal rings of influence by Progressivism and this has resulted in a new popular interest in actual reactionary politics as people wake up.
> everyone in Britain should be a conservative
This is important to understand because it is how we got here. Reactionary ideologies are not interested in global leadership, but rather local control. Progressivism is an expansionist ideology interested in global domination; which is why we are currently either all progressives or former progressives (like yourself).
