Touching or moving a hungry snake or one that has just eaten and is still in a hyped up hunting mode does up your risks of getting tagged in my opinion.
Nope no one is telling you that you've "screwed up". All anyone is doing really is expressing their opinions and sharing their personal experiences with feeding methods. In the end, do what works - for you and more importantly for your snake. As long as you've done your homework and fully understand the reasons behind why you make any decision about the husbandry of your snake, then it's all good as far as I'm concerned.
Glad to hear the feeding went well!
