Heritage - what bloody heritage?

I am, I think, quite aged. I have bits of memory that go back to 1938 and quite good recall of things since 1940. Mind you, this morning sometimes gets a bit hazy!
What I have no difficulty with is the way I was brought up. It was very much a case of 'children are seen but not heard'. My parents were above the normal age for parenting when I was born; my father considerably so. As an only child I had the full benefit of their attentions in ensuring I knew and complied with the standards of that time.
I learned that truthfulness was at the top of everything. This might be moderated by considerations of what was permissible in the way of conversation. 'That lady is fat' was possibly true but not permitted from even the youngest child. I was taught respect for my elders. How to approach them, speak to them – after being spoken to – and how to exist alongside them. My parents counted as elders and there was no relaxation due to familial relationship. Aunts and Uncles had to receive the same respect and consideration. Transgressions resulted in physical punishment. The punishment came first directly after the offence. No debate, no discussion.
I knew that provided I had said where I was going, I could be away all day playing in the woods and fields that surrounded our house. I was introduced to a shotgun at an early age – 10'ish or so. The rule was that if you shot it – you ate it. All adults could be trusted – almost implicitly. The police were regarded as friends and one was encouraged to say Hello when seeing one in and around the street. They always answered and often chatted with a young citizen.
Religion was of much significance. Just as important as knowing the tenets of one's own faith was recognition of other faiths and some understanding of what they believed. There was no clash over a person's choice of religion; that was respected.
Schooling was most formal. The idea that one would cause the slightest annoyance to one's teacher was totally absent. Avoiding school was not even considered. One did as one was told. There was little discussion as to why we learned what was put to us no matter how abstract it might seem. Most learning was by rote. Spelling bees were frequent. Reading aloud was common and we all knew our multiplication tables up to twenty times twenty. There were no exemptions from games and sports – all competitive – and those with sick notes still went onto the field and were chivvied around.
Around the age of twenty, I was conscripted into the Army to do a compulsory two years of service. I will not drag on as to what that taught me other than to say it must have been the best finishing school this side of Switzerland. I learned to be loyal and to understand what the loyalty of others meant to me. I became completely able to operate as a single unit with few resources as well as a team member. “Can do” became a watchword that was used to evaluate my personal and team performance. I saw foreign countries and observed how they operated. How the inhabitants inter-reacted and how they treated us – sometimes unwelcome in their land. From these experiences I gained some strong opinions – yes, maybe only just short of prejudice and bigotry.
Now, the world of my youth has gone. I cannot think of a single thing I have described that has survived. All swept away. I've gone back through the archives of the newspapers of those days and certainly there was violence, crime and social injustice. However, the spread of those olden days in no way relates to the parlous state we are in today. This is not just an immigration thing; the changes were wrought by those I would have to consider as 'one of us'.
However, those changes were to some extent benign. Just as people get the Government they deserve (and isn't that appropriate right now!), the community developed as the majority voice decided. I could regret it without understanding it or approving it. I adopted what I named 'reverse apartheid' where I did not aim to exclude people from my personal space and environment but I exiled myself from them.
However, I am now being reviled and threatened by people who are but fairly recent incomers to what was my land. They seek to implement massive change – indeed, the aim is to take the country's principles away and introduce a Islamic paradise. This is being carried out not just by obvious hotheads and terrorists with bombs and threats of chemical warfare on the streets of London. Muslims we might regard as 'nice old guys' are demanding rights and concessions that empower them but remove from me attitudes and conduct I have known and practised for over seventy years. Our smiley-face government has no experience of the attitudes that these disrupters have as their basic drives and cannot accept that there is a hidden agenda. Human Rights For All is the cry. Most of the things I have seen demanded conflict with what I regard as my Human Rights but I'm am told to grin and bear it. The status of refugee is, to me, clouded. Why seek sanctuary here when they have already travelled through three or four countries where, it seems to me, peace reigns? Having made the decision to travel to England as a 'nice' place, why set about destroying everything that has made it 'nice over the years?
