I've put this in General because it is not specific to either Hanson or any one artist / actor / celebrity, so please understand it in terms of that. However, I will furnish my question with two experiences so as to make the point of the thread clear.
Example 1: I told someone here that Abigail Breslin is my favourite actress and that I run associated fan pages. I received the comment "But she's less than half your age." (it was maybe a year ago - she's currently probably about 51% of my age)
Example 2: I was once asked why, if I'm not gay, am I a Hanson fan.
The logic behind both of these statements evades me. Being objective about the first example and not presuming that there was any insinuation, acting is acting, and if an entertainer is good at his / her craft then it will gain respect from people who follow their careers. As for the second statement - musicians make music. One supports an artist or band because one likes the music. Or maybe that's just me...
