I think a property owner has the right to decide (based on his religious and moral) whom he will and will not rent too...employment may be a different case....If Robert's worked to benefit the power of government to once again, tramble on property and personal rights...then we have a right to be concerned...If he turns into another Souter, you can kiss the base of the GOP goodbye....
The employer should be able to choose which candidate meets their needs for a job, and regardless of how it may interfere it should be the province of the employer to decide what might affect the job, it's not the province of the applicant or the government. Anything less is ANTI BUSINESS. (That's two strikes, he's pro gay AND anti business)
