As a British person I agree with your second point. Everyone should use Greenwich Mean Time which is obviously the correct time. Even if it means that noon is in the middle of the night for some people.

A very strange post. I live in a mid size English town (not a city) and can find all the cuisines you mention within a one mile radius of our town centre. Plus numerous others such as Greek, Turkish, French, Egyptian, Portuguese, Bangladeshi. Even American, god help me.

I can celebrate all the holidays you mention if I wanted to. Why wouldn’t I be able to?

You really need to get out more.

I’d be concerned that my own chatbot might get jealous
