How can I talk my friend into licking Hatsune Miku vocaloid 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 alisema 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 wewe 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 punda for not liking like...I dunno, I don't feel just 'cause wewe like anime...that means wewe automatically gotta like certain things. What should I tell my friend to get him back into Hatsune Miku Vocaloids?. I need all the advice and help wewe can give me. he was a Hatsune Miku vocaloid shabiki but not untile his Ex girlfriend told him things to change his mind about Hatsune Miku vocaloid and other things. I need advice and lots of help on what I should say to my friend to get him back into Hatsune Miku Vocaloids.
