One sibling became very ill, Grandparent cared for the child 24/7, took the child to many doctors in different cities, despite cost (which was a factor), and eventually donated a kidney to the child. The child survived, grew up, had children, remained very close to Grandparent. This child's daughter married a man of another race. Grandparent was not very supportive of this decision. Should the child who received Grandparent's care, and kidney, have cut off the Grandparent because of this? (That's not what happened, by the way).
There's "not supportive but accepting"
and
there's what OP is doing: not supportive, not talking with the brother, guilt-tripping him, judging his lifestyle as immoral, refusing to meet his partner.
If the former, I'd let it pass. Grandpa doesn't live my life, but I could maintain the relationship.
If the latter - yes, cut off. My nuclear family's well-being, especially my children's, take precedence.
