Hi Carl:
They are becoming more brazen every year. First I did notice "alien" dolls with big eyes and alien features; most of these are available in asia.
Then kids in school started reporting "hybrids" so close to human they could pass. However, they lacked knowledge of the latest rap groups.
Next came hybrids that are more alien and we are seeing some in groceries. This is a gradual process. Humans are being conditioned to accept others who are different and if any one complains that is hate speech and they are full of racism. Laws against illegal aliens are not being enforced any more.

Finally, the end stage will be obvious looking aliens living among us. If any one complains that will be accuse of racism. After all, we must accept every one.
