My parents are boomers and neither are grotty hippies. This forum is full of boomers who are rock solid conservatives. Is it possible you’re overgeneralizing?
Of course I’m overgeneralizing. But there really is a huge difference in the kind of worldview/mindset of the pre and post baby-boomer generations, and I almost always found conversations with the former vastly more interesting and rewarding. A stark, down-to-basics difference. Without things like pop-culture obsessions or self-absorbed pursuits. An undistilled ruggedness and outlook towards life.
