If you’re unsure of how America and his sister got the idea that gays are penguins/flamingos just google “gay penguins” and “gay flamingos”.
A lot of people have suggested that Sister America should be a hippie Liberal to counter America’s religious Republican, but I have to admit that I ignored those ideas simply because Sister America is far from a hippie.
But then someone came with the brilliant idea that she should be a Hollywood Liberal who like a parrot just repeats what others have said without really knowing what she’s talking about. That fitted perfectly with America who is just quoting the Bible without really understanding it.
I like to think of them as having the mentality of teenagers. They want to make the world a better place and think they have all the answers, but they have yet to understand how it all works. They'll get there eventually.
