Why would it reduce abortion? Please tell me how gay “marriage” or homo adoption or anything related to this perversion prevents abortion. Please do tell.
Saying that gays have a "right" to adopt puts them in the same line with heterosexual couples for a very small number of eligible infants and young children. A pregnant woman who has no control over where her child is placed might well reject the possibility of adoption--and perhaps even choose abortion instead.
Simply put, the greater the demand for those who want to adopt = decreased demand for those who are killed.
