We understand all too well. You do not understand. All life has value, human or otherwise. Its the human supremacy and arogance that is causing the issue.
Remember if cockroaches can out last us, we should not feel so high an mighty.
Humans can't even put the deifnition of what love is. Just look at the number of posts on this site when asked the question of what love is. Yet you dimiss any other living things as not being able to love.
A mother protecting its child from danger and giving her own life is what I consider part of love. Animals, especially dogs do that all the time.
Ah you see, its easier to build relationship with animals because they are very transparant beings. Humans are not. That in itself explain why it easier to build those relationships.
Does that mean I am not up to the challange of building a relationship with a person. Absolutely not, but it does not in any way generally animals are easier.
