I think you took that the wrong way. I think the poster was being sarcastic in response to a poster who was suggesting that certain people should be forced to go to the back of the plane. It would be a violation of the current rules for an airline like WN to require people with service animals to sit at the back of the plane. Plus the poster who suggested it seems to think that people will weigh the decision of taking a service animal vs. sitting in the front of the plane and that they all have a choice. The reality is some people need both a service animal and a seat near the front of the plane, especially if they have difficulty walking, etc.
