1) bullying is bad, anti-bullying work is important.
2) the more pink is used to represent femaleness, femininity, queerness etc., the harder it is to bust stereotypes about gender.
My idea of a pink day would be more like a sustained pink-busting explosion. Flash mobs of people wearing pink happening randomly all over for weeks and weeks. When asked why you are wearing pink, answer with one of these:
1) I like pink
2) I look good in pink
But maybe I am being curmudgeonly. Sometimes I experience serious pink fatigue.
