First, and this is just a pet peeve of mine, but when people ask for definitions of words and concepts they clearly understand solely as a (bad) debate tactic it's annoying. You know what God is, and you know what discrimination is. A better question might be "how does that create discrimination"
Second, I think the point Justin is trying to make is that putting things like "in god we trust" on money is an example of inscribing Christianity into public life, which should not be done considering there are many other religions. However, I do agree that it probably doesn't personally harm him, but it definitely has implications for groups that are negatively affected by what people interpret to be Christian values, such as LGBTQ people or people of other religions. The whole point is that glorifying Christianity as the religion of America by putting it on currency or in other places is the problem, as it certainly negatively affects people. (for example most arguments against gay marriage or abortion rights are religious in origin, and those arguments no doubt have harmful impacts on groups affected by those things, as well as the fact that the KKK, while being incorrect and not actually being good christians, ties american identity to the religious ideals that influence their white supremacy)
I understand "in God we trust" connecting the United States to monotheism, but I'm not convinced that it must be specifically Christianity. Even if it is, though, most of the founders and early leaders of this country were Christians or at the very least subscribed to Christian morality (Thomas Jefferson comes to mind). On that basis "in God we trust" is acceptable simply as a historic relic.
As to people being harmed, my Christian faith tells me that I need to love and accept everyone, but I don't have to love and accept what they do. It's incredibly frustrating when someone chooses to be defined by what they do, but I am nevertheless obligated to treat each person with the respect due a precious child of God made in his image. That extends to unborn children as much as it does to LGBTQ people and serial killers. If that hurts anyone I'm sorry, and I will do what I can to ease their suffering, but I'm not going to compromise and I'm not going to condone what I understand to be sin. Does that help explain modern conservative Christian political positions?
