Small little rant here actually, so sorry ahead of time.
But holy moly I get so irritated with shipping sometimes. Because I play Derpy and I do a series with Doctor Whooves and Derpy, I get the brunt of this quite often.
Now, I'm all for shipping Doctor and Derpy. It's my favorite pony ship. But good GOD does everyone have to be so assholishly RABID about it?! It's really freaking me out. If I put the Doctor with ANY other pony at ANY point, even if it's NOT a ship, people throw a giant temper tantrum "NOOOOO IT HAS TO BE DERPY THIS IS STUPID DOCTORxDERPY FOREVERRR"
It's annoying and extremely rude, okay? I cater to the shippers a lot. I have a few videos, images, and series which ship the two blatantly, such as the Derpy Love Story dub and Lovestruck Derpy. I love the ship but I also am open to other ships and can even enjoy them if they have logic behind them.
To be honest, I just like shipping the Doctor with all sorts of things. I like to play around. Understand that he's a character who has been in multiple different relationships, been married on multiple occasions (by accident and by choice) and he's got a lot of open ground and a lot of life in him. His companions can never stay forever, and neither can his spouses. He moves on, always, or they move away or get hurt. So people who ship him with Derpy... Are essentially setting the two up for inevitable tragedy. As he's said in show, "You can spend the rest of your life with me, but I can't spend the rest of mine with you."
So... Yeah... Just...
Stop being jerks about your headcanon ships. Please.
And don't harass other people just because they might not agree with it, either. Poor Doctor Whooves Adventures gets a lot of flack for having the Doctor take Twilight as a companion, and they havn't had any romantic implications at all. It's not fair and it's not right.
