Why do you think what bothered me was the fact this was a boilerplate? What bothered me--let me make it clearer for you--was the lack of specificity in the email, promising a wall, not some nebulous reference to border security. With the volume of correspondence coming in, I would hardly expect a personal reply.
This is the office of the President of the US so they will speak at a high level in terms of objectives and not details. The wall is just a means to an end and not an end to itself. The goal is border security.
