No, it isn't.  Saying something isn't a virtue doesn't make it a vice.  Preferring pepperoni pizza is also no virtue, but that doesn't mean I think it's bad.
My own preferences are also not in any way virtuous, they're simply what I prefer.  Hell, half the discussions in this forum over the past 20 years are simply reminding people that just because they like to play in a certain style, that doesn't mean it's any better than any other playstyle.  I'm sure MikalC's playstyle works just fine with his group, and I don't think he needs to change anything, but it would be a poor fit at my tables.
