The two events differ precisely in as much as they complement one another :
In principle: the annual LGBT Pride Day marches emphasize that Lesbians, Gays, Bisexuals and Transsexuals are proud of their identity and refuse to be shamed; The Global Day Against Homophobia highlights that in reality it is homophobia that is shameful and must be deconstructed in its social logic and fought against openly.
In practice: through LGBT Pride Day, we march in the streets in order to be heard by civil society; through the Global Day Against Homophobia, we act as members of civil society to bring debate into our institutions, schools, neighbourhoods, etc. As we can see, the two tactics are entirely symmetrical and complementary.
In addition, individuals who are concerned about the problem of homophobia, but who think that they may not have a place in the LGBT Pride Day marches, are nonetheless provided a means to voice their concerns through the Global Day. Similarly, but on an international level, in those countries where it is impossible to organize a LGBT Pride Day march, a campaign against homophobia may be undertaken on the Global Day Against Homophobia, particularly where, officially at least, homosexuality is not condemned through enforced laws. In this way, the Global Day may constitute a political lever in addition to that provided by LGBT Pride Day campaigns for individuals or countries that cannot (or will not) participate in the organization of Pride marches.
Together, these two events are necessary, symmetrical and complementary to one another.
