And to tell you the truth, you sort of brought this on yourself. I've noticed that in all of your Spitfire/Soarin pics you included RD in the background. That's most likely why everyone started complaining. If you're going to do a SoarinFire picture, then please do it without random ponies in the background. It draws away attention from the main focus and frankly it's really starting to irk me. I know you like Soarin x RD, and I won't rage at you for that, but please leave her out of these.
Take my advice: just ignore them. There are simply too many idiots on the internet for you to respond to or argue with them all. Or better yet, delete all the offending comments. If people started raging like five years olds on my pictures I'd do the same.
