Well, I was I did get fearful of People calling me a baby just because I watched it, so I didn't try to rewatch it (well, that and May came onto the show and I didn't like her portrayal, but that happened AFTER the incident at the hospital.)
Unlike most people, I learned of this thing, not from personal experience, but from a TV show.
In the PBS show "Arthur", Arthur often picks on D.W. for watching something known as "Mary Moo Cow" quite a bit of the time by calling her a baby (well, he more called it a baby show, but that's the exact same thing as calling HER or anyone whose seen it a baby). He has done this for several episodes that had Mary Moo Cow in it, even after he apparantly learned his lesson.
He even called that "Hopalog the Frog" a "Baby Book" (and consequently, called D.W. a baby as well), and he HIMSELF read that as his first book!
Plus, when they got to the whole "Love Ducks" episode, Arthur had watched Love Ducks (Ironically after dissing D.W. about Mary Moo Cow as being a Baby Show), he grew fearful about it, and when his secret let out, everyone laughed at him!
Thanks to those traumatic memories, I grew fearful of watching Pokemon due to that (Ironically, when I went into a fetal position due to fear in a childrens hospital when Pokemon came on, it also truly started my hatred for a certain female in AG). I may no longer fear watching it now, but still. Now, I also plan to write Marc Brown a personal letter mentioning my distaste for what he had Arthur do (I think he started it, but then again, PBS might have as well, since Arthur became an Independent tv show after he quit writing the books). It's actually developed quite a bit, but I'll wait on sending him the letter until i edit it.
so in that sense, no, I was never "embarrassed" about Pokemon, I was fearful of people calling me a baby for watching it, yes.
