Bringing up the Charles/tampon remark really is scraping the barrel. He was the victim of phone hacking. He didn't say he wanted to be a tampon, he said it would be "just his luck" if he did. Bloody hell, it was a bit of daft sex chat made in private.
If you want to talk about lowering the brand, a supposedly modern Prince, coming of age in the 21st Century and demanding respect in the army, publicly referring to a cadet as a P* and another as "looking like a rag-head", and
recording himself saying it, would fit the bill. Oh, and the RF, which he claims never supported him, made plenty of excuses for his racism.
I don't hate H&M. I think they are distasteful. As a woman of colour myself, I dislike their racism narrative. They have trivialised the word, lied about it and monetised it. He is not a good person WRT racism. I don't believe for a second he is some sort of reformed character, merely someone who has swallowed a critical race theory manual, and is using it to make himself look good, as so many white savour/SJW types do. There's no way anyone would be defending his past behaviour if it were not for his current marriage.
