If you tell a fat woman you like her because she's fat, it usually doesn't go well. They tend to ignore the "I like you" part and focus on the "you're fat" part. Only the very special and rare people of this community can accept something like that.

That's true, and it certainly does bear keeping in mind. Most of the time though, it kinda comes up in conversation, or I feel like it's time to share that preference with the lady in question, because I want to be upfront about it.
I don't think it's good for any relationship if you have to keep this part of yourself from them.
As someone who exclusively dates bigger guys, I normally tell them upfront that I like big guys.
But for the love of God, never tell anyone you like them because they are fat. Doesn't matter which way you swing. It will piss people off and rightfully so. Saying that is saying you only like them for how they look.
That is shallow as fuck, and prime dumping material.
