Honestly, I don't buy these gimmicky things where people do something gimmicky (Like go on a parade, or wear a certain colour of clothing), in order to 'raise awareness' about something. Most of the people forget the message and it's just a 'fun thing' for them. A much better thing to do would be engage in an activity where you're sitting people down and talking to them, having workshops etc, in order to educate them. Wearing high heels doesn't educate anyone.
