Fallacy name for an erroneous notion that favor in the interest of one party indicates a disfavor or disadvantage to another party?

I might think of this as a false dilemma: you're either for me or against me. Usually, there are more than 2 choices. What do you think?

That is, not all decisions are clearly one way or another. Maybe there is a solution that helps everyone?

I am not sure if I would classify this as fallacy. Rather, it seems more of a false assumption or even just an unsupported claim. My reasoning for this is that it doesn't pass criteria #3 (it must be deceptive - it is flat out stating the assumption). The important point, however, it to recognize that it is poor reasoning to make that assumption.

non sequitur....it does not follow that since someone has love for some then, therefore, it implies that someone necessarily has hate for others
