It's 'Murica!
Get over it!
I love these things, actually, because pronunciations are such an entertaining thing for people to get all riled up over! Especially when our cousins across the pond in England get involved!
English is the single, most b*stardized language on the face of the planet. It's origins lie with old West German dialects about 1,500 years ago. And along the way, the English language has raped, pillaged, plundered, kidnapped, stolen, and adopted vocabulary, syntax, and grammar from virtually every other language on the planet.
We'll happily incorporate a word into English and then argue over how it's spelled and/or pronounced until we're blue in the face, regardless of how it is spelled/pronounced in its parent language.
Like "herb". In the US, "herb" is pronounced with a silent "h" when referencing plants used in the kitchen for season. It's pronounced with the "h" sound when used as the name of a person "Herb", short for "Herbert".
Talk to our English cousins across the pond, and "herb" is most definitely pronounced with the "h" sound, period. And they'll gleefully make a big deal out of this, regardless of the fact that its origins as "herb" retained the silent "h" pronunciation.
That said...good English is a mark of a person's education and ability to communicate properly. Even so, given the immense complexity of the English language, which involves complex grammar rules, multiple definitions for many (if not most) words, and pronunciations that don't all follow the same linguistic rules, it's context as much as vocabulary and pronunciation which enables us to communicate meaningfully.
