To be fair, burms do tend to be pretty sweet it they're both used to be handled and not being manhandled. That said, the notion they make great pets for everyone is like saying macaws make great pets for everyone. You have to be able to house, feed, clean up after, haul around, and otherwise properly care for a potentially 16+ foot snake. Who can kill you (granted horses and dogs can also kill you, and tbh I think the bigger risk is an unhealthy or dead snake rather than a dead kid). Not to mention pay for vet visits which can cost thousands. Most people can't keep an animal like that, so temperament aside they do not make good pets for all but a few people.
The tegu and savannah monitor break my heart. He's right that they're intelligent animals, yet he neglects giving them anything but a hide and dishes. Certainly some balls and more things to hide in couldn't hurt, as well as taking them out to do more than just manhandle them (let them run around supervised, stuff like that). The monitor also needs much deeper substrate than that as being able to borrow is crucial to their health.
All that handling when the animals are clearly stressed is bullshit to. His dumb ass wouldn't get bitten if he wasn't fucking with them when they clearly wanted to be left alone.
Also, is it just me or do a lot of those animals look underweight? I'm no expert, but a lot of their spines seem to look too visible, and the loose skin on the burm and corn especially look off as fuck.
And all that kissing and slobbering on their heads. Thats almost certainly stressing them, and other than him getting diseases he could give diseases to them. Even with the best care, diseases can kill reptiles fast and are often undetectable until its too late (a somewhat internet famous 16 foot long Burmese python went from fine to dead in 72 hours due to resperatory disease, and this is with an owner who cared for her properly and the vet trying as hard as they could to save her)
Tl;dr, I think the animals are at far greater risk of him killing them than he is of being killed by them
On an unrelated note, I'm mainly an invert sperg as well.
EDIT: apparently the place he bought the black and white tegu is one of those skeezy pet stores that sell puppies (from puppy mills of course), keeps expired food on the shelves, and grossly neglects the small mammals.
