Why are people afraid of house centipedes? They already ARE cute! It'd be one thing if they were at least somewhat willing to bite you, like some spiders, but they won't. They've got the best eyesight of any centipede, which inadvertently gives them really cute little eyes too.
The reasoned par of my brain wholeheartedly agrees with you, and when I can convince myself to do so, I let them vibe. Unfortunately the reasoned part of my brain is powerless to stop the fight or flight response that happens when [spindly-legged creature] crosses my field of view. It simply happens.
If reasoning alone could overcome an otherwise unreasonable physiological response, then allergies wouldn't exist.
They creep me the fuck out. I know they're harmless and beneficial to have but when I turn on my bathroom light and see one on the wall above my toilet I have to get rid of it. They're literally the only bug that freaks me out, even roaches aren't that bad to me.
For me, they manage to trigger the "SNAKE!" and "SPIDER!" panic responses simultaneously. The rational part of my brain likes them, the instinctual part tells me to smash it with a rock
