Did YOU actually read the tink Progress article, or did you just gloss through. Here since you don't want to read, this is Mark Regnerus's own words:
I said “lesbian mothers” and “gay fathers,” when in fact, I don’t know about their sexual orientation; I do know about their same-sex relationship behavior.
Need more ?
"Within less than a month after Schumm (2010) was published, Gartrell, Bos, and Goldberg (2011) published a report online in which children, especially daughters, of lesbian mothers reported high levels of nonheterosexual sexual orientation and same-sex sexual contact..."
...But you'll need to check with ThinkProgress before forming an opinion.
2-Whether anyone likes it or not, any special interest group has the right to TRY to have a law changed.Does not necessarily mean they can automatically succeed.
It seems to me that quite a number of the Anti-SSM Crowd wants to prevent groups from even trying.
What I find lacking about this whole thing is that SSM has NOTHING to do with raising children since gays can ALREADY raise children legally without marriage even being in the equation. So marriage is not required for parenting.
