If you don't like people giving their opinions on your opinions why did you even respond? Just because one friend of yours has aggressive snakes and she happens to feed in enclosure doesn't mean that feeding in enclosure is causing the aggression. Her husbandry could be off. Thousands and thousands of people have snakes and a lot of them feed in enclosure. I've never not fed in enclosure and sometimes they don't get handled every day or every few days because stuff happens and I've yet to have one strike at all. My female normal, if I did try to pick her up while she's in feeding mode, would bite me. Call that cage aggression if you want, but I call it a feeding response and I"m damn happy about it.
