Oh it's necessary.
I could care less about you agreeing with me. That's your opinion on the cartoon and it's perfectly fine~
But on the other hand, shooting down my grammar on the interwebz is an offense to my intelligence, and sadly it will spark witty remarks such as a fiberglass tampon being stuck in your genitals.
I don't need an English lesson from a bitch with no sense of compassion. Kthx?
