Why do some people hate Jenny specifically for constantly chasing popularity and social status, but Blair (and most of the main/supporting characters honestly) do the exact same thing?

Getting pissed at Jenny for other reasons is fair but hating her for that reason alone is stupid. I will also say there’s a difference between holding someone accountable for their actions and hating on them extremely, and a lot of people do the latter with Jenny which screams victim blamer because she was bullied and manipulated by Blair and Agnes. While Blair is a super fun character and I love her style and drive/ambition, I have noticed a lot of her hardcore stans act like she’s completely perfect and Jenny is super horrible, I wonder if some of them were bullies in high school
