This is cool: wanting a couple to be together, thinking that Donnie is absolutely adorable and just wanting good things for him and his crush, and commenting on a piece of fanart that is clearly celebrating their (so far non-)relationship. All totally fine, I'm right there with you!
NOT cool: spewing hate and death threats at April for not fawning over Donnie, wanting Casey to die, although he hasn't made an appearance yet, slut shaming, prude shaming, and getting angry at April for potentially stealing Don away (seriously, whut?) or potentially breaking his heart.
there are forums, chat rooms, entire clubs on DA made for this kind of fan activity, so could you please, please PLEASE keep it out of my comments? I love to read all of them, but I hate to see the entire page filled with a hateful string of people complaining how big of a bitch April supposedly is.
so in short; April is cute and awesome and don't be mean when you comment!
