This is my first time hearing the British don't like saying Celtic. (I'm from the U.S.) There must be some history there?

[ablation]

As someone born, raised, and currently living in the UK, this is the first time I've heard of this. It's literally never come up or been an issue anywhere in the past 50 years I've been alive, and I've lived all over these isles. A bizarre OP.

[nephihaha]

It has been remarked upon a lot in Wales and Ireland in articles. Not bizarre at all.
