I beg to differ with you on there not being many bikers before the 80's.
That being said, I have no problem with the reasons anybody might choose to ride. Just the desire to have 2 fists in the wind (no matter how often) is good enough for me.
Instead of begging a better use of your time would be to check some facts.
Harley sold between 5000 and 15,000 bikes each year during the 50s and 60s, between 15,000 and 40,000 each year during the 70s and 80s, then after that production soared to six-digits, 100k, 200k, then over 300,000 bikes per year.
So that is literally hundreds of thousands of more people if not millions, parading around on Harleys wearing Village-People outfits than there were previously to 1980.
I don't have a specific problem with people because they ride motorcycles, but I do think that people who participate in fashion trends, those who jump into a "lifestyle" when it becomes trendy as motorcycling has over the last thirty years, are shallow, insecure and needy people who generally make anything they participate in less legitimate, and I certainly don't need their attention or time, maybe you do though....
I have been a first-hand witness to motorcycling over the last half-century or so, and am an enthusiast of it's earlier history, so feel free to ask if you need any more questions cleared up......
