Kootenai county, couer dalene and Northern idaho have actually become redder in recent years as a result of the American redoubt movement. Mainstream Conservatives are also being chased and voted out of the idaho GOP by more nationalistic elements. You see this in the election result trends. Idaho is not turning blue any time soon. The real issue here is that normie Democrats have become radicalized. So whilst 75% of people in kootenai are voting red you still have 25% of the population who number a few thousand who are going to turn out for a trans or lgbt event even in a solid red state. In terms of the arrest thing. I'm guessing the trans gay event had a permit and hence the police protected them. I know antifa travelling in from portland and oregon were also picked up on the city limits by police. Couer dalene pd were basically intent on there being no trouble from either side.
