Being against pie charts is a great example of mid-wit (angry, ranting about nothing). The anti pie chart crowd recognises that other plots can achieve everything the pie chard does, and more. But the fail in this understanding is the assumption of "more is more". Sometimes you don't want readers getting down into the details. Sometimes you don't want readers comparing the relative sizes of pie segments (which the human eye tends to do on bar charts). Sometimes pie charts just suit the overall layout of the document they're part of.

tl;dr be mindful there's often a better plot to use than a pie chart, but if you want to use a pie chart, go for it.
