I can’t imagine why it would.
I don’t default to using my kneejerk, emotional reactions as barometers for the morality of other consenting adults’ sexual preferences, regardless of how foreign they may be to me.
If you are inclined to learn about it, as I was, there’s no shortage of light pieces written about how the Daddy/Little subset of BDSM kink isn’t about literal parental relationships or pedophilia, but about dominance and submission, which is a pretty common variant/preference among healthy adults.

In short, I tend to err on the side of not judging as bad (or good) consensual sexual relationships that are not recognized as problematic or oppressive and, quite frankly, are none of my damn business.
