This word is not common parlance in the US and I won't pretend to understand the additional layers of context in the UK, but from my perspective, if you're saying you love this, you love being this, why would that be seen as insulting?
And even if I personally didn't like it, why would I think I have the right to censor others' opinions about or or tell them how they need to feel about it, that they must have the same opinion as I do, and tell them if they can't or can't sing it?
Why would I think the world has a duty to insulate me from hearing anything that makes me uncomfortable, or that I have the right to demand the world reshape itself to my particular sensibilities?
This does not make sense at all to me, and does not comport with reality in any case and is not useful as such.
