One thing's for sure. You can't go by looks when trying to decide if someone is "into" reptiles or not.
At the reptile pet store I work at there is woman who comes in but looks like your "typical" grandmother. When she first came in several years ago, I expected to hear tons of phrases out of her mouth like: "The only good snake is a dead snake.", "People actually buy these things?", "Who would have a snake in their house?" and etc. I never in a million years dreamed she would like reptiles and then fill her house with them. She went around oohing and aaahing at EVERYTHING. I don't know how many herps she is up to now but it's a lot. She has bought snakes, tarantulas, turtles, lizards and amphibians, you name it. She also goes to the reptile shows now too.
Then sometimes we have tattooed, long-haired guys who run screaming like a little girl if I take a hatchling corn snake out of its container.
Now that is funny.
On a side note when I spell checked this post it highlighted HERPS and the first suggestion for a correct spelling was HERPES. I got a chuckle out of that.
Here's a pic of me with my newest BP.
