I honestly don't get the mentality that an influential band HAS to be respected. If I don't like a band, why should I suggest that they would make MY hall of fame?
In your example, most of the people spouting 'But look at their influence' are by the people who actually genuinely like the band, and are looking for a reason for people to vote similarly beyond personal preference.
EDIT - Or else you get a situation that people were complaining about before... Only the Sacred Cows making into the HoF, and no one of interest or variation making it through.
