I’m a bi-centennial baby myself. My first bike was a Western Flyer Buzz bike. I remember when in the ‘80’s sportifs became all the rage around here. I’m of the opinion that the Olympics had something to do with that (‘84). Admittedly for the inclines in this area that Buzz would have been a chore to ride but what it lacked in gears it had so much in style.73? A baby! A child! I was born in 72. So, as your elder I will say that I never had a muscle bike either. I got into them from the restoration side. Something cool for my kids that just grew with a mind of its own. My thought: Build what you like. One of my muscle bikes will have some suspension, but the way it's used doesn't make it an off road bike. So, depending on what you want to do, you can decide the category. Just because you're not into muscle bikes doesn't mean you can't build your version of one and love it.
