If you were an employer and your job applicant exercised his/her right to not turn in your EEOC-required race survey, how would you feel?

The EEOC requires all American employers to collect data on race. When a job applicant is newly hired, s/he will typically get handed some forms to fill out, including the W2 IRS form and a race survey so they can report the results on their EEO-1 form.
It is mandatory for the employer to hand you a race survey.
But it is totally optional for you to fill it out and turn it in.
What if you were an HR director, or an HR worker, or a hiring manager and your new hire refused to fill the form out (as it is his or her legal right to do so).
Would you secretly judge the person as a racist? Or a potential troublemaker? Would you be worried that most fill the damn form out without question, but this new hire is thinking a bit too independently?
