I whole-heartedly disagree. It's important to take a stand against ineffective, borderline-illegal screening processes used by employers.
People who frequent HN may not be subject to this problem as much, but in general, most of the power in an interview is concentrated at the employer's side of the table, rather than the applicant's. For them to abuse that power by prying into people's personal lives is unethical and unfair.
Hiring managers should know better, but it sometimes takes push-back from the community to help them see the issues involved. The recent change in policy in Bozeman shows that such feedback can be effective.
