Yes, I could respect the beliefs and actions of other life forms. I get along with my dogs and cats quite well. I can communicate with them and they can communicate with me. I also used to care for larger animals and they are not too different.
It doesn't really take much intellect to know when another creature is happy, hungry, uncomfortable, sad or angry. It does take some empathy and respect for their lifestyle. One must work within one's own limitations as well as the limitations of the other life form. To work with dolphins, one must adapt to a liquid environment for instance.
I actually wrote a poem about this very thing! http://hubpages.com/hub/Spave-Travels
An ambassador must be able to separate beliefs and attitudes from actions. If your attitude is that speeding in your car is ok for you, then your belief is that you are a safe driver. If you see a cop and automatically slow down, your actions will change. But as soon as the cop is gone, your attitude and belief that speeding is OK kicks back in and you speed up.
So, anyone that wants to communicate with foreign ideas and beliefs must be able to do the correct actions whenever their own belief and attitude is quite different.
An open mind would be essential. Refusing to judge others by "normal" criteria would be required. Empathy would come in handy. Having a thick skin would be standard, suppose the aliens didn't like you personally? You would have to step back. They might actually think humans smell bad or something equally repulsive.
Interesting question, Druid Dude. I shall do a hub on this...
