He was just giving the info that in his opinion cage aggression is a myth. You gave your opinion too. I do not think anybody was upset. OP for the record it is your choice to feed in cage, or out. Be aware you can sometimes stress your snake by moving to another area to feed. Then again, no matter the issue there will be different opinions. Just like a rear end, we all have our own opinion. You can ask as many questions as you like and there will be lots of advice, just take them with a grain of salt!
