I really don't think that is the bigger picture. The bigger picture is the right of individuals to practice their faiths (or none), their sexualities, and their cultures free of the external and very often ignorant commentaries and prescriptions of others. That's not a dig at you, it is a wider comment/observation.
I would place the disproportionate influence of Christianity across the British Isles a very significant distance behind that of, in no particular order:
2. Social media
4. Advertising industry
5. Music industry
9. Apple and Amazon
10. Trade Unions
11. Large corporate industry
The central and core message of Christianity is love. Everything else is embellishment - both right and wrong. What are the central and core messages of the organisations I have listed?
