What sucks is that people attribute stuff like that to the whole generation; we get painted broadly as very right wing conservatives who are against any social programs. But look at things like the age demographics of the last couple presidential elections. Yes, you'll see that more older people voted conservative than liberal, but not by a large margin. You'll also see that, though more younger folks voted liberal, that margin wasn't huge either. And in our society, it's not unusual for folks to get more conservative as they get older (the opposite for me personally, but it's often true), so it won't be surprising if younger folks today vote more conservatively when they're older.
Huge hunks of boomers are fighting for equal rights for all people, are big proponents of social programs that help those who are disadvantaged, advocate for universal healthcare, and all sorts of other progressive issues. Large numbers of younger people are against those things. The fact that total numbers might tip one way or another doesn't change that, and applying a stereotype to millions of people is always wrong.
