There are events to stop homophobia, like the "gay pride parades" and "International Day Against Homophobia" on May 17. It was first celebrated on 17 May 2005 in more than 40 countries. Argentina, Brazil, Mexico and Colombia have developed mass media campaigns against homophobia since 2002. In some places, it is illegal to treat people badly because they are homosexual, and it is a hate crime to hurt them for that reason. Laws against such discrimination have been made in several countries. Internationally, the Declaration of Montreal and the Yogyakarta Principles were adopted in 2006.
