Insulting someone's intelligence

Apparently, if you take AP/IB Bio, the you are lazy and dumb. I'm highly lazy, but I'm pretty occupied on social media. But I certainly don't need ANYONE to call me dumb. Do not insult my intelligence. At all. And yes, I have Tina moments, but they are meant to be fun. You calling me dumb and thinking that you're one of the smartest people in our class is not fun. I don't appreciate it when you just target a group of people just because they have an interest in Biology. I guess if you were dying one day, your classmates would not bother to save you since you called every single one of us Bio kids dumb. Sucks to be you.
