stop saying that whitney slams mariah on the bridge

I was shocked when i see whitney fans saying that whitney slams mariah on the bridge..on the contrary..i thought that whitney was shouting too much...good singing is not about singing louder..it's about technic and emotions..SKILLS!! not loudness...i'm a whitney fan and i hope whitney did not sound that loud..and i ashame that some of you guys actually think it's good that whitney slamed mariah..because..that's not artistry but just trying to sound louder..
