Why do so many of you support adult/child relationships???

14 year old dating 26 year old. "Who cares! As long as you're happy!" Wtf?

16 year old with 30 year old. "Age is just a number, don't listen to haters!"

"I'm 18 and with a 40 year old, I'm glad you are happy"..um you're an adult dating an adult here..

What's wrong with you guys?? This isn't ok..why is there so much support for child/teen dating an adult?
