My opinion about equal adoption

I’m against of the equal adoption because is illogical that a child has two mothers or two fathers.
A child needs a mother and a father, not two fathers, that’s bad for the children.
When he or she said “mum”, would look at the two mothers or the two fathers.
The mother’s teaching is totally different if compared with the father’s teaching.
This can affect the child psychologically and not accompanied by any good. In conclution, the equal adoption can affect the child and shouldn't be allowed.
