Good idea.
Lets get the progressives on record as being religious bigots.
The question is whether a prospective justice is capable of leaving his or her religious views outside of the courtroom and making legal determinations in an impartial manner. This barrett has made no secret of her religious views and could be placed in a position in which she could inflict them on all Americans. I live near D.C., and I can tell you that scalia made religious speeches all over town and allowed his religion to govern his decision making. He did not make any attempt to even appear to be impartial.
The other day, I posted a link to the transcript of the oral argument in the Texas
Whole Women's Health case. The justices who are known to be "conservative" did not ask even one question of the person arguing on behalf of the law in question that dealt with the substance of the law, even though major medical groups like the AMA and the American College of Obstetrics and Gynecology had already filed amicus briefs that totally rejected and undermined the "medical" claims being asserted by the state. This is an example of people appointed to the high court who cannot do their jobs.
It is not religious bigotry to ask whether a judicial nominee is capable of being impartial rather than being an activist for his or her religion.
