Yes,but adoption isnt always the wiser method,for multiple reason
Influence,STDs can affect them,MRSA,etc can be passed down to them by even hugging their own parents.
And another thing is, Homosexuality is causing many kinds of STDs to spread.
And a few claims they make is
'Animals change gender so transgenders are okay'
Wait so the reason alright,The Frogs,etc change gender,is because they have chemicals triggering this gender change,humans dont.
'Homosexuality is natural cause animals do it'
STUPID, if you put a supposedly gay animal in a room full of female counterparts of that animal, the animal will most likely breed with the woman instead of the man, so Homosexuality is enviromental,not natural.
And No claiming moral superiority for not being against them wont work against facts.
