Explain to me the concept of cookies of different flavors

From Fandom wank wiki

A wanker throws a hissyfit over the idea that her friends have journals on sites (mainly JournalFen) of which she is not a member. She accuses them of purposely excluding her and expresses bewilderment as to why people would need to visit two journaling sites. This idiocy produces the cookie analogy. Mmm, delicious.

Hey now! Wait, explain to me the concept of cookies of different flavors. I mean, if you can enjoy all the same great things with ONE type of cookie, why would you want several flavors? I mean, if it's all the same, and you get the same benefits, what's the point of it all? I mean, not that I want a different cookie or anything because, y'know, I already have a cookie and am completely happy with it. I just. I don't understand. Different flavors? Taking TWO cookies of possibly different flavors? Why? WHY? The choices! For the love bob, WHY?

But I'm curious, yo. I mean, I don't don't want a cookie myself. It's all in the name of scientific curiosity. And when people eat cookies that are different than mine... I start to worry. I feel like I can't trust anyone I know that eats different cookies than I do. I mean, what if they're all getting together to come up with the best cookie EVER! without me, or... what IF, they're not eating cookies at all? What if it's all just a conspiracy to make me think they're eating cookies when they're eating pies instead?

I mean. It's completely impossible that people would like a little variety in their cookies from time to time. You mean double chocolate chunk doesn't make you orgasmic every time you eat it?
