Explain the causes of the public reaction associated with the red scare

Fallout Lore!!, just kidding. The US became very patriotic but was also constantly worried about the threat of total atomic annihilation. This caused many somewhat wealthy people to build actual fallout shelters in their backyards, especially during the fifties and sixties. Other than people almost constantly worrying about the cold war going hot, I can't think of much more going on at least in the US

whole lotta ptsd going on

in the 1800s, chinese workers migrated to the united states, first to work in the gold mines, but also to take agricultural jobs, and factory work, especially in the garment industry. chinese immigrants were particularly instrumental in building railroads in the american west, and as chinese laborers grew successful in the united states, a number of them became entrepreneurs in their own right. as the numbers of chinese laborers increased, so did the strength of anti-chinese sentiment among other workers in the american economy. this finally resulted in legislation that aimed to limit future immigration of chinese workers to the united states, and threatened to sour diplomatic relations between the united states and china.
