> So, if the author really thinks that animals are a bigger problem than TSA, they are probably one of those people who "cheats" security by paying for pre-check to avoid going through proper security.

As opposed to someone who brings an "emotional support" animal with them to cheat their way through security?

The main problems I have with "emotional support" animals is their owners. These people are usually inconsiderate of others and completely self centered.

I've witnessed on multiple occasions dogs shitting or pissing all over commuter trains and their owners just hop off the train and leave it for everyone else to deal with. You'll often see these people at the gate trying to get priority seating by shoving their dog in the attendent's face while the attendant is trying to help other passengers with legitimate needs. I've been nipped by one of these dogs on a flight and the owner's response was "she feels threatened by you." I suggest she might put the dog in her cage since I can't move seats at which point she tried to have my seat moved by an attendant.
