1. The aliens are not necessarily our friends. They may not even think in terms of friends and foes.
2. They are in our own galaxy, not across the universe. They are, in fact, as close as the wart on your nose, astronomically speaking.
3. There is no reason to believe they are more advanced than we are. It may be that their only technology consists of microwave radio transmission and reception.
4. It is absurd to tell them all the faults of our civilization(s). Are you trying to scare them or what?
5. Racist and sexist? These are highly arbitrary assessments from a very narrow political perspective. Besides, the aliens probably will have no equivalent of race and sex and they won’t know what you’re blathering about.
6. Don’t you think it’s a bit much to expect that their civilization, if any, would have any relevance to us? Since they are not human, they won’t possess human nature or any of our characteristics.
7. Please try to make this a little less political—okay?
