Miley Cyrus is letting the world know that hate shouldn't be tolerated ... and also that she supports same-sex marriage. The 19-year-old songstress is flashing the peace sign, and a black bra, while posing for the NOH8 campaign.

The campaign, created by photographer Adam Bouska and Jeff Parshley, is a "photographic silent protest in direct response to the passage of Proposition 8." Prop 8 says marriage should be between a man and a woman.

Way to take a stand, Miley!
