Fat logic, fatlogician (fatlogicians)

  As a philosopher I'd like to tell you that there isn't logic that is "fat logic". There are many others like: Formal logic, Informal logic, Symbolic logic, etc (Learn more: https://en.wikipedia.org/wiki/Logic). Fat logic (or 'fatlogic') is just a neologism (neologic term), created by some fatpeoplehater (i.e. sizeist, weightist); there is a Reddit subreddit 'fatlogic' (i.e. r/fatlogic). The same case is with the words fatlogician (pl. fatlogicians).

 I'm against the sizeism, weightism, racism, zodiacism and the other discriminations. But it doesn't mean that I'll accept the obesity. I'm doing my best to be in a good shape. And also, I'm honest when someone is asking me about his or her body. For example, right now, I got a photo of an obese young woman. And the question was

What do you think? Thoughts?

and my honest answer was

An obese girl.

It's useful for the obese people to know the truth and to take some measures against the obesity because it's not healthy at all. At least they can start with increasing the sport activities and counting the calories.
