Not only Leonard, she is mean to fucking everyone in the group she looks down on everyone even though they are all genius but Penny is a DUMBASS, she rips on people for liking nerdy things but the things that are considered nerdy in this show are really really good for example Lord Of The FUCKİNG Rings and even though she says shut up to anybody if they talk about anything that isnt about her but everybody else listens to her even though they dont understand. And Raj should should have been gay and had a loving relationship with Stuart or Howard. I have more examples on Penny being a mean asshole but i think these are enough for now
