NK obviously believes that attending this protest on Shabbos was the right thing to do, presumably because of pikuach nefesh.
As stated, you’re welcome to argue that with them or to post your opinion that it was not necessary, etc.
But not to call them goyim for doing what they consider to be perfectly permitted and, in fact, even required (pikuach nefesh).
The only knot tied here seems to be your long rambling post.
