The "Epic" - Part of "the record as a whole" or not?

The Supreme Court specifically states that it will not take into account the contents of the "Epic", the rant on Westboro's webpage attacking the Snyder family, despite the jury and the courts below discussing it in their decisions because the petitioner did not mention it in his writ for certiorari.  Therefore, "[t]he epic is not properly before us and does not factor into our analysis."  FN1

While the petitioner's brief may have only addressed claims dealing with the picketing, throwing out any claims to do with the online rant against the Snyders, should the epic have been thrown completely out of the record and not even viewed as evidence as to the specific intent of the church to prey on private citizens' pain and suffering as opposed to speech protected as matter of public interest?  Rather should the Court have taken the epic as part of the record as a whole when determining whether the picketing near Snyder's funeral was a "subject of legitimate news interest, that is, a subject of general interest and of value and concern to the public," or a personal attack on private citizens?

Here are some of the contents of the epic as cited in Alito's dissent.  I find it difficult to contemplate this lovely tidbit not being a part of the record that the Court claims it looked at as a whole.

“God blessed you, Mr. and Mrs. Snyder, with a resource and his name was Matthew. He was an arrow in your quiver! In thanks to God for the comfort the child could bring you, you had a DUTY to prepare that child to serve the LORD his GOD-PERIOD! You did JUST THE OPPOSITE-you raised him for the devil.

.....

“Albert and Julie RIPPED that body apart and taught Matthew to defy his Creator, to divorce, and to commit adultery. They taught him how to support the largest pedophile machine in the history of the entire world, the Roman Catholic monstrosity. Every dime they gave the Roman Catholic monster they condemned their own souls. They also, in supporting satanic Catholicism, taught Matthew to be an idolater.

.....

“Then after all that they sent him to fight for the United States of Sodom, a filthy country that is in lock step with his evil, wicked, and sinful manner of life, putting him in the cross hairs of a God that is so mad He has smoke coming from his nostrils and fire from his mouth! How dumb was that?”
