"You have lumped everyone that has chosen to put the sign up into a basket of your creation."

This is interesting; I feel the same way about the "lumping" by sign-bearers of all who disagree with the heart of their pronouncements... A "basket of deplorables," so to speak. ;)

"Come and knock on our doors and I bet you would find a huge spectrum of life experience, motivation ... humanity."

Again, the same as you would discover in those who find your signs "problematic," as they say.

By the way, I'm not sensing a lot of humanity lately in the "science is real" crowd. Their overwhelming support for vaccine mandates reveals a disturbing lack of empathy and comfort with authoritarian overreach.
