Greta Thunberg - why would she be regarded badly?

[StrawberryDream24]

I've just met someone who was extremely scathing of a woman dressing as Greta Thunberg for an "inspirational women" dress up type thing.

She didn't elaborate, other than that it was ridiculous for someone to have done that and she had to hold her tongue in telling them so (and the circumstances allowed for no further discussion for me to find out why she felt that way).

I don't know a great deal about GT but what is this lady on about? Has anyone any idea? Is there something I'm missing?

Whilst I'm not particularly fond of the type of individual the term describes, I've always been a bit hmm as ultimately any derogatory insult based on skin colour isn't great. It's just that 'gammon' usually refers to comparatively privileged individuals within the hierarchy of victimhood so it gets ignored.
