I think very few people are undecided about these things. These are &quot;gut feeling&quot; judgments. What is the appropriate trade-off between security and freedom? What is an acceptable amount of immigration and how much should we require people to integrate? Nobody sits there and does a cost-benefit utilitarian analysis of those questions, if one was even possible. They start with broad principles (e.g. surveillance is <i>per se</i> bad) and interpret facts to fit into their preconceptions.
