@Zoe: As someone who's done a lot of overcoming the past year, I don't think I'd ever get over my inborn automatic response of trying to kill Gordon with the nearest heavy object. Then again I'm so ridiculously arachnophobic it probably qualifies as something more severe....
I've had to eject two Huntsman spiders from the premisses recently. Catch and Release.
They can give a nasty bite, hurts and bleeds a lot.
I've also dealt with two redbacks. Their bites would be (not could be, would be) fatal to my in-laws, both in their 90s. Those arachnids didn't get caught, they got neutralised with extreme prejudice.
Was I scared? Terrified, actually. But it needed doing.
One can, to some degree, overcome one's instincts. It helps to know that those instincts are causing you to act counterproductively, and
this is important dammit!.
Catching the huntsmen - both as big as my hand - gave me the screaming meemies. After transition, I acquired arachnophobia I didn't have before - some neural re-wiring from the hormones I guess. That was unexpected, and I only became aware of it when visiting a friend's house, seeing his "dangerous spider recognition chart" (as I'd seen many times before without thinking anything more than "how useful") and nearly screaming.
The joys of living in Australia.
My bet is that if Gordon's life was in danger, and you knew for a fact that he was a person, you'd pick him up and take him to safety. THEN collapse in a screaming heap. Amnesia-inducing drugs would be appropriate therapy.
