I can see both sides but every individual has to decide for themselves what level of risk they want to deal with. I can read my animals well, and there are times I would let them near my face and times I wouldn't. I've also seen people on youtube who are really trying to teach others to keep the animals face away from yours, and in the very process of doing so they are making quick movements towards the animals face that if the animal was going to get fearful and bite ever, this would be the time for it to happen! I think it's good to teach as a general practice not to have them near your face because a lot of people don't know how to read their body language. How many times have you heard "Aww look, my BP is waiting at the front of his enclosure for me to take him out because he misses me and wants to cuddle!!"?
