Welcome back! That story about your dad is a trip
while my Mom was the one who got me into The Beach Boys at a very young age, I remember my father would remind me that The Beach Boys were a bunch of drug addicts (which I couldn't believe because their music was so wholesome and I knew nothing about the history of the band. Also I was too young to fully know what drugs even were haha).
As someone who still constantly puts his foot in his mouth (or at times acts disrespectfully toward other posters), I completely understand that feeling of embarrassment about posting....but it's a very good thing: it means we actually care about being wrong/right and we are aware of our behavior. When I'm wrong or have an overly-blunt opinion that gets called out, it usually puts me in check.
Another thing I've realized in this fandom is that even when you are told you are wrong, you may actually be right. There is so much disinformation about this band that spreads around, publicly and privately, some that still has yet to be corrected. Something I have learned to do is check multiple sources, use common sense, and always research
where your information is coming from. Also, it's a big band with a big history, so there will always be multiple perspectives to each and every story. Anyways, my point being that there are so many different facets to this fandom, it's easy to feel overwhelmed, but overall it's such an awesome world to explore.
I think I was 20 when I first joined this forum and at the time I felt like I had too thin of skin to stay here. So I can't even imagine joining at 13!
One thing that has never changed, however, has been my love for The Beach Boys and their music.
THIS. They will always be my favorite band. I'm just so glad a lot of great people share this same love for this band that I do.
Again, welcome back.
