I am a newbie here too and my 50+ impression of the folks in this forum is the same as some of your students. I like reading (and once in a while participating) in the discussions here. I especially like hearing from folks that are new to biking and are interested in doing more of it. Actually, I quit road biking in my early 40s (and just toured for many years) mostly because I didn't want to be associated with a biker attitude that didn't represent me. I am glad to say that my 50s are the "rise above it" years and I really don't give a @&$% what anyone else says or thinks anymore. I have finally realized I can't do anything about it anyway, and being annoyed by it is just a waste of time and energy. Now, I just want to ride!
