Interesting post thank you for your ideas.
I agree culture and sense of identity can be strengthened in this way however I don’t see how this can save us from the demographic problem. If other cultures outbreed us we die out regardless of how we feel about our culture. Perhaps indirectly this would help if it made people more likely to fight, to support harsher rules on immigration and benefits to migrants?
Good point that the lack of a written constitution is a big problem. Things worked ok with a homogenous population but it makes us more vulnerable than other countries and more reluctant to enforce our values on incoming cultures as nowhere is it written that those are our values. I need to give this more thought but my initial reaction is that I disagree that it is those institutions that make us who we are. I think they contribute but you could keep them and still end up in a religious hellhole. Imagine for example the monarchy converts, parliament becomes majority Islamic, sharia law enacted and Christianity tolerated initially. You have technically preserved all those institutions but in reality have saved nothing. Whilst I would not want president Blair I don't hold the monarchy in high regard, I get the impression they see us as interchangeable plebs and do not forget Charles wants to change to defender of the faiths plural. I think they would happily convert to Islam to save themselves. We need to get rid of FPTP for the parliamentary system to work; it no longer functions as a democracy. I live in a safe seat so my vote is worthless. Rule of law yes we need to ensure it is applied to all; however, the rule of law is now being abused for example with hate crime legislation to silence dissent. With Christianity I can see value in some of the traditions and morals but only with the power of the church constrained considerably as it has been for the last 200 years or so. Go back a few hundred years and Christianity was killing heretics and scientists. We had to fight it then and must always be vigilant against religion trying to take power again. In conclusion, none of those institutions are things I would be willing to fight or risk my life for.
I think Enlightenment values are among the most important to European civilisation and what distinguishes us from other cultures. Scientific enquiry, empiricism rather than superstition, philosophy, freedom of speech including the right to ridicule monarchy, the government, and religion. Those Enlightenment values combined with the country-specific history, culture (music, ballet, literature etc), social conventions (British politeness, sense of humour) are what I consider worth saving (not forgetting the people themselves). I feel the Enlightenment values are (or were) common to all European countries and so would be a good starting point for a pan-European collaboration against the threat. I believe we need to defend the existence of nation states and in that respect some of the institutions you list are important as integral parts of a self-governing British nation state.
I agree it is important to educate ourselves and help other people question the mainstream narrative. To enaable others to see the value in our culture and not blindly accept what they are told has the potential to be very powerful against the corrupt leaders and their mouthpiece. I will make more effort when talking to others but it is a fine line to walk to not end up a social outcast.
These are all good things, I can see how they will help put the shallow consumerist culture into retreat but sadly think they will stand no chance against a violent fecund religion. Looking at other countries you can see it is a numbers or rather % game as to which culture dominates.
