You do not have to justify that your phobia is valid. It is what it is, and nobody should make fun of you for that.
I, too, have unusual phobias. I am TERRIFIED *phobic* of fish, and I'm scared (not quite phobic, though) of perishable food and food that could contain the salminilla (sp?) virus. VERY afraid. And I have my reasons. I also am very nervous about houseplants (not afraid so much as grossed out by them). Sound strange? It wouldn't if you knew my history.
I guess what I'm saying is that I understand what it's like to have fears that sound strange to some people, but that doesn't mean your feelings are not valid. Your feeligns should be respected, and I'm proud of you for standing up for that. I had to do that myself, with my roomates and it isn't easy.
From one petrified phobic to another.... you were very brave to talk about this.
