I would respectfully disagree. I don't think there is such a thing as "right" or "wrong" tastes, barring, of course, those that are harmful to others.
I would just think of my past self as someone with a different opinion.
Also, he ate way too much candy and left me with the obesity. What a dick.
For example, in the last few years I've shifted hard away from multiplayer games to single player games. I wouldn't say it's a more refined or "better" taste, just a different one.
Yours is the more universally accepted sentiment, for sure, and mine is an unpopular opinion, but I've just never been able to buy into that, personally.
Who's more right or wrong is ambiguous and can't be measured or proven, but I think that some opinions/preferences are still more right (or at least, involve more meaningful reward) than others. After all, I can remember the explosive exhilaration and magical feeling I got from stuff as a kid but no longer do as an adult and compare how powerful it was with the different stuff I like now. Personally, in hindsight, I don't think the former compares favorably at all, despite being more dramatic, noisy, and obsessive.
Weird example, but for me it's like.... someone who likes roller coasters arguing that they can get as much reward and satisfaction out of riding a roller coaster and having fun as anyone else can.... I don't know, falling in love and raising a family or something, and claiming that it just comes down to subjective preferences that are equally valid. I don't think that's really true-- Sure, they're completely different experiences, but there's a limit to what something can give you depending on what it does. While you can get something out of a roller coaster that's serviceable, give you a big reaction, and that you might lose and stop appreciating as you move onto other things, the possible reward there is still ultimately pretty trivial and limited no matter what your preferences are or how hard your biases/comfort zones cling to them, IMO.
I prefer to think of it as "I think you're less right about these things, you think I'm less right about those things, one of us is probably closer to the truth, but we have to accept that we can't know for certain who and not take these suggestions too personally."

For the record, I've grown more and more of a preference towards single-player games as well and tend to scoff a bit at the big addictive online multi-player stuff, but there are probably reasons why that's the case-- Reasons which have to do with my opinion/realization of what I think makes them more rewarding. I could turn out to be totally wrong of course, but I don't think it's a case of every subjective perception/preference being equally true/meaningful/valid.
Sorry for the sidetrack.
