@Lostandtired1 - Sorry, but am I understanding you correctly? Having a Disney themed wedding or wearing a Mickey Mouse jumper is 'encouraging infantillism'?! Seriously?! Is it that alien to you that adults could just enjoy Disney, without it being weird?! Why is it up to you to call someone out on it because YOU personally don't think it should be accepted in society? I'm struggling to understand what exactly you are getting at here.
I have two children, I'm happily married, I run my own business, but I like to listen to Disney music and wear jumpers with Disney characters on them- sometimes even when I'm working in front of clients! What exactly about that is causing a problem in society?! Who am I hurting? What is the issue? I am fully aware that I am 34 years old, and I am also aware that Disney isn't actually magic, but I like it, it makes me happy. I would have loved a Disney themed wedding, but I wasn't brave enough, largely due to opinions like yours, so I settled for a Disneyworld honeymoon instead, and it was amazing.
If you think that is 'blurring the lines between children/adolescents and adults,' then I assume you have a HUGE issue with the vast majority of children's clothing which are very often mini versions of typically adult clothing? Would you rather I wore a cropped top with stripes, over a jumper with Minnie Mouse on it, would that make you happy? You say you don't care what others wear, but you seem to have very strong opinions!
