The governmennt should not regulate religion, but members of government should not leave their faith at the door for policy making- they have to vote in accordance with their faith.
“It is never appropriate for a judge to impose that judge's personal convictions, whether they arise from faith or anywhere else, on the law.” - Amy Coney Barrett
I have a similar belief with politicians - you must have your first focus on the good of others and the exchange of viable ideas and solutions, rather than personal convictions.
