This is from the slut walk. One of the arguments is that girls ask for rape because they wear slutty clothes, short skirts, tight, low-cut tops. This girl is an example of the fact that rape victims can look like anyone. Girls like these are my heroes.
If you don't like it, go live your life while I live mine by dancing like a fool, singing when everyone has stopped, sharing random facts, being that weird spazz who has fun, and loving every single bit of it.
