In Belgium?

We appreciate the effort, but isn't this kind of like the Nazis marching in Skokie, in reverse?

A pro-family group has organized a march to protest a Belgian Parliament draft proposal to legalize homosexual adoption. Although Belgium has had legal same-sex “marriage” since 2003, the law currently does not permit adoption by same-sex partners. In addition, a birth within a same-sex “marriage” does not impute affiliation, thus the same-sex spouse of the biological parent has no way to legally claim parental 'rights'.
