Ok. Socrates, I'll be brutally honest, I don't like you. I never have, and I probably never will.
But regardless of my opinion on you, please take no offense to the following...
Your view of reposts are bullshit. Anybody that's been on imgflip longer than a year can say that reposts are the single most annoying thing to ever exist. Even worse than IceCube, ISISMemes, and a whole lot more. They show that the creator is either a. stupid, b. not creative, or c. just mean. And yes, before you say it, I am aware that some reposters have noble intentions, as you said and I quote,
"we don't know motives - there could be good motives for a person doing the same thing (e.g. it could be because they enjoy the joke and want to share it again, or they think they can make it slightly better because it fits a different template better, or they have some other idea about it - and those are legitimate things to do with memes)."
That is a great point, and I have done that plenty of times! I often find hilarious posts from iFunny and many other places on the web, so I share them. But, as you damn well know, there are people that do NOT intend to do good with these reposts. They use them for point steals, for ego boosts, to boast, or even just because they want to start a flame war.
THOSE ones are the ones I can't stand.
Nextly, I strongly disagree with the bottom half of this post. You labeled me as a "repost whiner", which means you are referring me to the bottom half. And boy, if there was a Top 5 Most Featured, I would be in it. You know nothing. You come prancing in here as a new account and shoot to the top faster than anyone, and before you know it, you've got dozens of users kissing your ass. (Don't deny it. Have you seen the comments? You and Raydog are the most over-glorified users in history.) I know see how the notorious DownvoteFairy felt about me. Holy shit, it's annoying.
So, to conclude, I'd like to say that not all reposters are being jerks; some of them have noble intentions. But if they don't, you do NOT have the right to label someone as a whiner.
TL;DR: Your post is shit, your opinions are shit, and you're shit.
