It is not right to discriminate against someone on account of their avatar, whether its TDA, Choobie, Nanachi, or otherwise.

You ought to have learned by now that it's what's on the inside that really matters. It does not take a considerable amount of Intellect to simply wear a typical booth or miscellaneous anime avatar simply because it fits in with the crowd. These outliers have not done anything wicked. Have mercy on them.
