How did calls to “contain” communism (containment) spill into many realms of life, including debates over the “proper” role for government, labor unions, gender, ethnic and racial groups?

Did you read the article on McCarthyism that I posted for you earlier today?
What did you learn from that article?
I learned about how Mccarthyism (containment) stripped people of jobs (blacklist for actors/entertainers), homosexuals/"sexual s" lost jobs, government was destroying peoples reputations and employment without good reason, etc..

I just skimmed the article because it went into much detail I didn't necessarily need. What I didn't really find was how containment spilt over into labor unions and ethnic/racial groups (besides maybe the fact that immigrants/non-whites were considered less loyal to the US/un-american and therefore they were thought to be more radical and faced containment that way?
