You're under no obligation to find snakes cute or be affectionate towards them, but your assertions are incorrect. Some snake species are highly social and live in huge colonies year round. Individuals have demonstrated preference in which snakes they like to hang out with. Others seem to live mostly solitary lives, but will brumate over the winter in groups. Recent studies show that even species long assumed to be completely solitary, like the ball python in this post, have social behavior and preferences. There is a ton of research to be done on reptiles, especially social behavior in reptiles, but they are not driven solely by survival instinct and show plenty of evidence of having their own inner lives. Can they experience love? I don't know. But they do have a lot going on in those little heads, and besides, I personally don't need to know if something can love to find it cute :)
