I totally agree. If there is anyone I am more thankful about outside of my immediate family and friends I would argue that its Walt...........and let's not forget Roy too! But Walt first and foremost.
But to the OP, it seems to me that you have a family that actually does LOVE Disney, but seems to be ashamed or embarassed about admitting it. That's too bad because I grew up going to WDW as well and I can always talk to my parents (and now wife) about those wonderful memories anytime. Isn't that the point?
You don't say if you are married, but my guess is you would marry someone who shares your interests of Disney or who has never been like my wife had and was interested and now hooked too!
Look, I'm a 31 year old married man with a 6 month old son. I look like I could be a linebacker in the NFL but two of my favourites hobbies are Sports and Disney. Find me a stranger that likes either one of them and I've made a friend. That's how I look at it, why waste your time with someone who ridicules you about it? Life is too short, there are plenty of people that "get" what you are talking about, and I am one of them.
By the way, we've been to WDW twice prior to our son being born and we plan on going to Disneyland for the first time in April - alone. Anyone that calls me crazy, is jealous, simply put.
