For the love of science, please, please, please stop quoting Leviticus as some sort of "gotcha" for Christian beliefs. As an ex-chrisitan it makes me cringe everytime I see it. It's way too long for me to want to explain in full, but a majority of the laws you find in the Bible can be explained away as either made moot by the sacrifice of Jesus or explained away as "different time, different place." These laws were put in place to set God's chosen people apart from other and to protect them (don't eat shellfish, pigs, or carrion b/c those animals carry disease). There are so many laws in the Bible that Jesus had to dumb them down to 2. Love God and love your neighbor (your neighbor being literally everyone else).

You really want to hit a Christian where it hurts? Ask them how they have been loving their neighbor. Most Christians I've encountered don't read their Bibles. To them, their religion is more of a brand than a lifestyle. I've met people who identify as Christian because their parents were, despite never setting foot in a church. In order to become a Christian, you need to confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead. While it's true that good deeds alone don't get you into heaven, the act of following Jesus leads to the performance of good deeds. So again, ask how persecuting LGBTQ+ is loving your neighbor? How is actively voting against the institution of social programs loving your neighbor? How is disowning your children for not going to church loving your neighbor? God's love my ass...
