One doesn't spend a few centuries in Makai without picking the local habits.
Not to mention that if Byakuren really wasn't sealing the various youkai she met, then nobody in Makai knew her. Therefore, they probably only saw her as a nun, and harassed/tried to eat her.
I guess she had to figuratively break open a few skulls to be respected, otherwise she would've became the local cum dumpster.
