Why don't you actively campaign for a set of laws on patriotism, which would oblige people who want to live in UK to comply with. From what you have said that appears to be what you want. I for one would not object to that. I spent 30 years working to uphold and enforce the laws of the UK and took an oath to the Queen to do so.
I now live in Spain and I show respect for the country, which I believe one should do wherever they live.
The main problem is that many people get confused between 'what they think the law should be' with 'what the law actually is.' At present there are no laws which require citizens to be patriotic. If there were the police would enforce them.
