"They" don't have anything to do with having these children. Cheney had to obtain the MALE components of procreation to father the children. Her "partner" had absolutely nothing to do with it.
No, they do not.
Cheney conceived a child with the help of a sperm donor.
This "Heather Poe" creature was not involved in the process.
And they aren't married, either, regardless of whatever perverse activities they engage in, or whatever farcical ceremonies they may have performed, or whatever risible government paperwork they may have filed.
They are twisted, deluded, unfortunate souls who are seeking affirmation in their mental illness rather than getting the help they desperately need.
May God be merciful to them ... may He grant them the grace of repentance and conversion.
