Just because people are younger, doesn't mean that they don't know what they're talking about when it come to politics.
But most American adults don't even vote nowadays. For example, according to a U.S census in 2014, a mere 42 percent of Americans voted at all: “Only 42 percent of Americans voted in the 2014 midterm elections, the lowest level of voter turnout since 1978”(http://america.aljazeera.com). Because of this, the government has taken it into consideration to make voting mandatory. Making voting mandatory could drastically cripple the freedom of speech, and break the First Amendment.
