Nothing about having you own clothing line or label makes you authentic. Is Donald Trump authentic for owning his own real estate empire? Of course not. Success doesn't automatically translate to authenticity.
An authentic person is someone who people respect for their honesty, integrity, and/or their openness. With the Barneys issue, the lack of creativity in his lyrics, and the Samsung deal which lead to most autopiloted album Jay's recorded to date, Jay's definitely lacking in authenticity these days.
Yeah I don't see why dudes are taking this personally like the survey is about their family member...it's not saying anything about Jay's music, his business ventures or his life, just saying that some people don't think his art is authentic. I don't see the big deal cause it's not hurting his bottom line at all. If that's how they feel, that's how they feel
