Is the trolling justified?

Lately came across this lady’s page who uploads these snippets from her makeup and beauty coaching classes (I am assuming). It seems she is from a small town/village and so are her students. The amount of trolling and ridiculing she is getting in her comments is insane! People with blue ticks and huge followings are trolling her left and right! So called makeup artists are having a field day in her comments section including big names like Guneet! But is this fair? How is this even a fair comparison? It’s actually heartening to see young girls trying to be financially independent by learning such skills and this might be their only source. People are trolling her looks, her accent, her methods and what not! When did we become so cruel! One starts at some point and only then makes their way up forward - that’s how one learns isn’t? It’s heartbreaking to see the sheer lack of support here! She deserves better.
