You think it's ironic that people with fences around their houses think a 1,954 mile wall 30 feet high is impractical? What makes that ironic?

Are you suggesting that in these heavily walled Southwestern cities, people are using fences primarily as a form of defense against immigrants, and it's therefore ironic that they think their home walls will successfully protect them from large scale immigration, but not a wall along the border of two countries?
