You don’t have to agree upon everything. As a professional web developer you are the advocate of your visitors’ interests and needs; you have to protect your understanding of good user experience and make sure the visitors will find their way through (possibly) complex site architecture.

In fact, it’s your job to compromise wrong ideas and misleading concepts instead of following them blindly.
In this context nothing can support you more than the profound knowledge of fundamental issues related to your work.
