The accepted answer to this question says
Since the electroweak interaction is mediated by spin 1 bosons, it is the case that "like (charge) repels like and opposites attract".
Another answer comments:
The Higgs is spin - 0 (scalar field) and the graviton is spin - 2; attractive.
From this other question
a force mediated by a spin-0 scalar is always attractive.
So what's going on here? Why does the spin of the boson determine whether the force is universally attractive or follows the opposites-attract-and-like-repels-like pattern?
What would it look like for a spin-3 or spin-4 boson, if such a particle existed?
