No, there are arguments (I'm not saying good ones) for why gay parents are different. Traditionally fathers and mothers have had different roles, this is cultural, so what happens if a gay couple adopt and don't adapt to cover the traditional role of the other gender. To use an out-dated (very) and somewhat sexist example, how will the son of lesbians learn to hunt animals, how will the daughter of gay men learn to make clothes?

While I don't agree with these arguments (for the record, I'm gay), it would be possible to make them without being homophobic. Would they be made in nobody had the beliefs you describe? Perhaps not, but they could be.

Trqditional roles are really quite a weak notion. There is huge variance among parenting styles across the population.

Just no being a drug-addicted and not having a debilitating mental disorder is enough to be an above-average parent.
