Here’s the answer to your question and @Whitefire13’s point as well.
Verbal resistance toward an idea is not tolerance. Just as it isn’t toward Jimmy in painting the room green or MLK in fighting for civil rights.
Theism receives, in the least, verbal resistance from it’s ideologies; therefore, it is not completely tolerated in this country. I could pull up youtube examples of this if you’d like but I"m sure it’s unnecessary. I’m not debating whether it should be tolerated. But rather that in many circles it is not.
