How can I talk my friend into licking Hatsune Miku ボーカロイド again? My friend his Ex girlfriend talked him out of licking certain things.

This is what my friend told me that his Ex girlfriend told him. Eh, it was a good thing in a way. Kinda taught me that there's a dark side to the whole thing
There's people that are WAYYYYYYYYYYYYYYY too into that shit. I 発言しました to my friend. yah ignore that I am way to into that. Anybody can be way into anything. And my friend said. I'm saying that for all type of things, bands, games, movies, all that there's always the people that are wayyyyyyyyyyyyy too into it. And I said.yah I know what あなた mean. but does not make it a bad thing. Meaning Hatsune Miku. Heck your Ex probably did not like her. Also why I kinda don't like it is because, it's kinda one of those things people get on your 尻, お尻 for not liking like...I dunno, I don't feel just 'cause あなた like anime...that means あなた automatically gotta like certain things. What should I tell my friend to get him back into Hatsune Miku Vocaloids?. I need all the アドバイス and help あなた can give me. he was a Hatsune Miku ボーカロイド ファン but not untile his Ex girlfriend told him things to change his mind about Hatsune Miku ボーカロイド and other things. I need アドバイス and lots of help on what I should say to my friend to get him back into Hatsune Miku Vocaloids.
