Focus on the Family makes no such claim. I don't know if the Houston Chronicle got it wrong or if the PFLAG spokeswoman did, but this is misinformation, especially in light of the accusations of "lies" and "myths."
I would tend to blame the PFLAG spokeshuman (are you sure she's a woman and not one of those other genders?). The Houston Comical isn't any different than the rest of the MSM but this is typical of PFLAG.
As a side note, when you have the truth on your side you don't need misinformation.
Shalom.
