Firsat off most of these girls join at 14 and 15, some younger, I don't foresee them finding a partner that young.
Whatever the case may be, that's for the individual (and their parents) to decide. You don't see a company dictating the course of a person's love life as, you know, an extreme violation of personal fucking privacy? You know, just a little bit.
Plus this is really just business, as their image affects the company,
"Fuck personal privacy and human dignity, honey, you've got a brand to represent." Lovely.
However, each group makes their own rules, it's like if I join a group or team, they have rules & regulations to follow.
The issue isn't that groups can have set rules and regulations; the problem (which you don't seem to grasp) is that these rules cross a boundary and violate a person's privacy in an extremely disturbing manner.
"the land of the free" (bullshit)
Woah, guys, stand back, we've got a real rebel on our hands.
Except smoking is a public health concern. You know, second hand smoke and all. While it may be contestable, at least there's an understandable, reasonable justification there. As far as I know, "second hand sex" isn't doesn't exist - barring the easy masturbation joke.
In this case, it affects it negatively because it will enrage some of the fans of the group who then might stop buying their CDs.
I'm sorry, but who the fuck doesn't buy an artist's work because they have consenting sex with a partner, and why the fuck are they being catered to?
