The McCarthy Era was one of the darkest periods in U.S.
history. The government was so intent on
flushing out communism that they disregarded the rights of its citizens. It was a terrible time to be different or
speak against the government. Those who
did were already put under suspicion.
Many who were put on the blacklist during that time suffered a lot. Some lost their careers while others were
imprisoned over hyped-up charges. If
there was anything we need to learn is that we need to protect our freedoms of
speech, the right to fair trial and the right not to be subjected to unlawful
arrest.
