Ok, so I just watched the video of the interview, and this is my review of it.

Several puns related to cannibalism and/or pedophilia ("are you hungry now?" then a complicit gaze ; "you're just seeing parts...of the body of work" she then nervously laugh ; "please enjoy", "and I did enjoy" ; etc)

She says that the song Bon Appetit is about sexually empowered liberation (my translation= "we should be able to enjoy cannibalism and pedophilia, right?") while Chained To The Rythm is about mental political liberation (my translation= "I can't wait for a satanic new world order!")

She says "I love, you know, a consensual interaction. There's nothing wrong with that, we're all animals!". Ellen then replies "nothing wrong with that... ga ga ga ga ga!"... (To me, it sounds like she's imitating a baby... It's almost a confession in my opinion). Katy then put her head down to laugh, is she embarassed of what Ellen just said?

The way she talks about consensual interaction looks to me like an argument in favor of normalization of pedophilia. Like, if the child is consenting, there's nothing wrong with it. (forgetting that a child can't "consent" to that sort of thing without being confronted to it first... So, without a crime being committed first)

Katy then talks about her partnering up with Boys & Girls Clubs of America. (http://archive.is/XDWRa))

The logo looks a bit like two hands in each other and 3 bands each way. If someone can analyze it better maybe?

"In partnership with Katy on her new “Witness” album and tour, we #WitnessTheFuture where all young people, especially those who need us most, can reach their full potential as productive, caring, responsible citizens."

Especially those who needs us most...

"Boys & Girls Clubs provide safe, fun and affordable places for kids and teens to go during out-of-school time, where they connect with caring mentors, make new friends and get access to life-changing opportunities."

Connect with caring mentors... Life-changing opportunities... (I see a pattern here, with all those organizations...)

You add to that : the video for Chained To The Rythm where you can see the double pink heart logo, and the reference to "playing ping-pong all night long" in This Is What We Do (this is what who does what? the song never tells...), it seems to me Katy Perry has become the favourite puppet for satanic propaganda...

Edit : maybe I should post it in "pizzagate whatever", not sure?! Some of it is my interpretation, but Ellen imitating a baby when they're talking about sex really creeped me out, that's why I decided to post it.
