When the lives of 23 million sick and uninsured are at sake, I'll say what I please.
Are you one of those people who has been denying that 7 justices in 1973, almost all of them Republican, ruled on Roe v. Wade based on their "understanding of the law." Oh, no! You call them murderers, baby killers. And you have been fighting for 47 years--some people who allege they are pro-lifers have even bombed abortion clinics. One even murdered a Planned Parenthood doctor who was ushering at his church.
You don't respect their "understanding of the law," so why should I respect Amy Coney Barrett's. She has made at least 3 comments attacking the ACA. She is a wealthy woman whose husband is a partner in a law firm. She is able to outsource a lot of her child rearing and household tasks to paid help (or perhaps the older children are raising the younger ones, which is what happened in my friends' homes when they were kids.) We are in a pandemic. 209,000 people have died in the U.S. (worldometer.) Many are poor and people of color. And she doesn't believe health care is a human right.
She signed up to work for the worst president in our history, who will almost definitely face a grand jury in NY early next year. She accepted the post even though early voting has begun and some people have already cast ballots and Trump has no business appointing anyone. She belongs to a suspect covenant church group (which, BTW, is ecumenical, not Catholic, according to its website and membership.)
And so yeah, I can question her integrity. And since the "People of Praise" are not a Catholic group, but a mixed bag of people including Pentacostals and fundamentalists, no senator is anti-Catholic for questioning her loyalty to the Constitution.
