My mother is petrified of snakes.

I handle this by not having my snakes around her. Or really even discussing the snakes with her.

Strangely, this has made her less terrified and generally more accepting over time. Somehow, knowing I'm around them and they haven't eaten my children and other pets is reassuring, when in the absence of having them shoved in her face.

My husband just plain doesn't like snakes. Not afraid just very "EH". I handle that by not forcing them on him or asking him to take care of or interact with them. Also, strangely, he's gotten better and has developed a fondness for our little Calking, all on his own.

I know you're not getting respect from these people with your issues/allergies with dogs, but what's that saying? Two wrongs don't make a right? Seriously, you're just escalating the situation. Some people are PHOBIC of snakes. It has nothing to do with rationality, it has nothing to do with logic, and it has everything to do with being an innate, illogical, fear that is hard if not possible to overcome. We're not therapists. We're not providing exposure therapy to them with forced interaction. Some people just don't like them. You're not helping them, snakes, or the hobby by pushing the issue. You may be making phobias, apathy, or dislike WORSE by pushing the issue.

You are certainly harming your relationships by making it another point of contention or using them as a 'get even' weapon or to make a point.

Let. It. Go.
