The media have been determining the behavior and thoughts for a LONG time..and not just politically.
I know that women have developed eating disorders from decades ago...when the media decided that Twiggy was the "it" girl...
They have just gained MORE power as time had gone on..and more importantly, they have less scruples, so they don't even try to hide their partisanship regarding politics anymore.
For sure, it's high time we counter them.
