Ok people, it looks like there is a need for some "agree to disagree" action around here.
While it is true that not supervising a live feeding is irresponsible, that doesn't mean that someone can't feel uncomfortable while doing it! On the other hand, just because it may seem easier and more comfortable to feed f/t doesn't mean that someone who feeds live is doing the wrong thing.
Just because you disagree with someone doesn't mean that their opinions and feeling are nullified.
It is not wrong to feed live, or to feed f/t, it just comes down to the needs of the snake and the personal preference of the owner.
