You're not offering criticism of her opinions. You're just mocking. Defined as “making fun of someone in a cruel way.”
You repeatedly post that silly sticker out of band, as if only to say ”I conform! I fit in here!”
I was taught that if you see someone mocking a little girl — being a bully — you stand up as a man and say: Hey, that's not OK.
I'm not going to argue with you. If you want to be a punk and dig in, just to try and fit in with other man-childs of the internet, then by all means, do you.
