I definitely agree that more exposure and maybe 'safe' exposure like video and photos are good.

I don't have a spider phobia, in fact funny story I have a spider that made a web on my dashboard of my car and I've left her there all Summer, she has been catching bugs for me, and I smile at her when I'm driving about.

But, some things give me a bit of phobia like I'm not a fan of centipedes.
