Keep posting! You could be the lynch pin that sways an opinion or two. Be proud of your little friend and totally ignore the negative comments. I never take them personally. Fear of snakes is a very real phenomena for a lot of people, so don't feel like they are just hating on you.
In the beginning, my snake pics scored tons of hateful comments. I just happily kept posting and ignoring. And now? I get comments like "i don't typically like snakes, but yours is really cute", or "i never liked snakes before, but Neptune is so pretty".
Infuse some anthropomorphism into your pics ... "look at my girl, she's so embarrassed because she tipped her water over!" "here's my little noodle with her puppy dog eyes wondering where her sweater is because it's Fall now"
Dumb stuff like that - people love it! LOL.
