That was the motto of humanity since time immemorial as people act entirely on self-interest, a behavior which formed the base for our family unit, and organization from tribes to modern nations and conflicts.
Denying this would be denying our history and what makes us human.
Which specific facts and feeling are you talking about?
Also, regardless of which, both facts and feeling don't matter in the real world. What actually matters is the enforcement at your disposal that you can use to uphold either of them, typically by force and violence. Because facts without force backup to match are always destroyed by feelings that have the superiority on force projection and violence.
Like for example, Galileo was right in his facts, however that didn't stop the church from burning him at the stake. And the world of today is really no different. Like Ghaddafi and Saddam didn't in fact have WMDs, however that didn't stop Bush and Obama having them killed over made up bs, and getting away with it.
