OP between this and you're other thread you're doing yourself and Susie (potentially one and the same) no favours.
It's clear you seem to believe #BeKind is a free pass for anyone in the public eye to avoid criticism.
In the case of the two people you have mentioned:
Susie - most of the negativity relates to the quality of the service provided, specifically the "over priced" "bespoke" styling service which is allegedly anything but (rather a generic style guide pdf), plus her response to that criticism which rather than to address it and take reasonable action she allegedly chooses to block customers who complain or respond rudely.
As for criticism of her personal style - well if you put yourself out there as a stylist then people critiquing your dress sense comes with the territory. It's not about being kind/unkind, potential customers and the wider public have a right to have a view on what you are selling.
Jack - if I posted that I didn't like XYZ recipe by them it's not unkind to say so. Yet again Jack is selling a product that people are well within their rights to discuss its quality.
Further to that Jack has used the public platform they created due to their recipe books to air very strong political opinions.
There's nothing wrong with that in and of itself, but if you are happy (as Jack is) to throw multiple aggressive salvos at people with differing political viewpoints then it's hypocritical to suggest those who lob opposing views back with equal vigour are being unkind.
I'm not suggesting that some of what is written about these women has on occasion not been unkind - certainly comments about physical attributes are both mean and unnecessary and I absolutely condemn those types of remarks.
However, the fact of the matter remains that whatever the intention of #BeKind it seems to have morphed into a meaningless virtue signalling hashtag largely utilised by people who could do with being kinder themselves or used as a tool to prevent fair and reasonable discourse about people who've put themselves in the public eye and feel aggrieved by any less than affirmative interaction.
