I'm a liberal. I don't care if Barrett is Catholic, Jewish, Muslim or Hindi. I don't care if she comes from a Catholic, Jewish, Muslim or Buddhist town. 
What I do care about is whether she will issue rulings on the basis of her faith or her impartial understanding of the law. Now what is pertinent and what those senators were getting at is that numerous groups take serious issue with Barrett because she fails this test. Barrett has repeatedly given interviews and lectures in which she implies her faith may be a more guiding principle than the constitution and the law. Shes opposed Roe v. Wade, she's opposed same-sex marriage, she's opposed equal protections for LGBT persons, and she's supported the Hobby Lobby ruling.

There's real issues with this nominee to the 7th circuit, so lets focus on the "loudly" part of Sen. Feinstein's question. Its not just living, its living LOUDLY and PUBLICLY from someone who needs to be an impartial arbiter.
