Is Hillary Clinton deliberately trying to alienate the 18-25 demographic?
Yes, kids shouldn't be playing violent video games any more than they should be watching violent movies. The fact that this bill singles out games, however, brings back strong memories of the Comics Code Authority and the movie censorship of the past. It smacks of politicians trying to exploit parents, and all it will do is alienate game consumers (who are likely to behave as single-issue voters in this case) without swaying parents (who have other things to worry about.)
(If Sen. Clinton wants to fix something that screws with teenagers' values and identity, she should look to commercials, rather than video games. The unrealistic expectations born and bred of advertising do more harm to more young people per day than violent games will do per decade.)
