I think a lot of us feel frustrated with Gemma for her attempts to present a carefully curated lifestyle that, at best, just isn't accurate and, at worst, can be very damaging- i.e. her disordered approach to eating. Coupled with the nonsense about manifestation, lying about things and her inability to take criticism, she's made herself quite unlikable.
However, I do think that Khy's comments overstep the mark and come across as venomous and quite vitriolic. This is a space to vent but I feel sometimes certain comments and phrases can overstep the line into bullying. Calling people out is one thing. Calling people names and abuse is another.
