First of all we put something to rest once and for all. No one hates Sharon. I don't know what you are seeing in her thread but literally anywhere in the internet in any forum i have been, in any comment section no one hates her. People might not be as invested to her since we have seen so little but that isn't "hate".
So when i see people asking "why so much hate" i want to choke a kitty. 3-4 negative comments in ONE forum don't justify the word "hate". For a character to be hated the majority of the comments about him or at least half of them should be negative. So, don't make generalizations and create notions. No one hates Sharon. You are jumping into conclusions way too easily.
