LOL you're funny. xD I really really hope you succeed.
I'm a ShinRan fan too. It's kinda sad cuz I'm 18...haven't been such a big fanatic of anime couples for a long time.
Anyway, for the question that someone posted earlier, I have a few other reasons why people might prefer ConAi. Even though I'm absolutely against this pairing, if the anime was different, I might think diffferently.
Usually, when it comes to anime or manga, I tend to admire female characters who are more reserved, cool, and depressive. And I would want her to end up with someone who's witty, laid-back with a good sense of humour and smiles a lot. It's mostly because I'm so tired of seeing naive and ultra-cutsie main female characters. They annoy the heck outta me. So to cut the story short, this type of "mysterious girl with happy-go-lucky boy" pairing is pretty rare, but very much so in demand. I'm not sure about what other ConAi fans think, but these are some of the reasons I can relate to.
But despite my description of my ideal female anime character, I love Ran because she's not a ditzy, innocent, whiny girl like most manga heroines. She's such a badass whenever she does her karate thing; the girl has personality! She's so loyal to Shinichi, and yet she hides it well whenever they're with each other. This makes her on par with Ai when it comes to the level of "unique-ness" of their characters. Shinichi matches her well, because although they're not complete opposites of each other (like ConAi), they're extremely compatible, and could be very good partners in catching the bad guys. Shinichi can be the detective and Ran can be the cop.
Between ShinRan, it wasn't love at first sight, their love was accumulated for many years. And for that reason, even if Ai loves Conan, her love for him won't ever be able to compare to the love Ran has for Shinichi.
