The focus on Gabbie's (and other - especially - female yourtubers' physical features) is part of the larger systemic issue of society's biased focus on women's physical appearance. I know Jeffrree Star's forum critiques how he looks, but there is something so much more... focused when it comes to female youtubers on this site. And someone like Fouseytube who literally tatoos a hairline on his bald head gets nothing mentioned. It's clear gender bias. And it's not just Gabbie's forum, either.
Yeah, a lot of youtubers change their physical features with fillers and botox and plastic surgery, etc. But that's because society has a magnifying lens on them, and expects them to maintain a certain look. The fact that we are critiquing their faces and bodies is but another symptom of this issue, and further pushes these standards on them... and us, by extension.
So, maybe, we can stop with the screenshots and the face/body shaming and just focus on the content and the personality, instead?
