What "originalist text"? The Establishment Clause, even under a reading which doesn't call for a wall of separation, provides that the state cannot endorse religion. A stone monument listing the Ten Commandments, including the jealous-God ones, standing in a court of justice is quite reasonably an illegal endorsement of religion. Moore was in fact removed twice from office for showing his contempt for the rule of law.
Now that's certainly my opinion, and one that is widely shared. But how does such opinion qualify as "hate"? Conservatives these days whine as much or more as liberals do. 
The text provides the State cannot endorse A religion over others. By some estimates, there are thousands of Christian sects, and at least seven major ones. None of which have been endorsed over the other, nor has any other religion been endorsed.
But, as I have pointed out, the Decalogue is common to not only Christianity but Judaism as well, and by no means an exhaustive list of the sectarian rules which abound in Christianity nor a complete listing of Jewish Law, so the monument to the first widely acknowledged code of law in the Western Heritage that does not involve doing violence for violence (that was Hammurabi), is acceptable as not only a basic code of law, but the fundament upon which rest our Statutes: a monument to an historical milestone.
Or would you repeal those pesky Christian laws which prohibit murder, theft, adultery, and such, because those have a religious basis?
If we can live with them from the State, then certainly, we can live with them from religion.
There is no Constitutional Right to be free
from Religion, only that the State will not make one religion official, not require a religious test for office, and not interfere with the free exercise thereof.
Any time the atheists and agnostics want to put up a monument to their religion, they can, as far as I am concerned, as soon as they figure out how they would memorialize nothing.
We may all walk past monuments we find offensive, for whatever reason. I am not a fan of enshrining a Communist on the Mall just because he got shot. I can't really demand the removal of that monument, but I will cheer the productive pigeons which alight there. Perhaps those who preach diversity and tolerance should practice it.
