It is, for lack of a better word, "disappointing" when your family and friends don't also like reptiles.. Or even worse, when they actively dislike your hobby. Fortunately for me, even when my family doesn't like the snakes, they don't say much about it.
For my part, I don't subject them to the snakes when they're over. Unless they ask to see them, the snakes stay tucked away in their room. I am lucky that my husband also likes the snakes. He's not as into them as me but he does like to handle them and feed them, etc. The rest of my immediate family, however, has a negative reaction to them.
I would just suggest that you don't take the snakes out around these family members, but occasionally mention snake stuff around them and maybe one day they'll start asking questions and it might go somewhere. I agree that the low-maintenance aspect of the snakes can be a good "selling point" and also that they are free of odor and don't make noise. These talking points do seem to make people perk up. I also usually make sure that I have some photos of my snakes on my phone so that if someone acts even the least bit interested, I can pull up some pics to show them.
