Yet another reason why I prefer to call myself a casual MLP FIM fan. Many bronies who spout this mantra often don't live up to it. When they say it, I will often assume they mean the opposite. This phrase means nothing to me because it got trampled.
Ever see a picture of a humanized pony? Notice how bronies will attack artists who draw the mane six as anything other than straight, cisgendered, white, skinny females.
No, that's not loving or tolerant to "take a stand against forced diversity". What is "forced diversity" anyway? To them, it's when anyone draws Fluttershy as (for example) of middle eastern descent in a hijab just for fun.
To me, it's when you actively force headcanon onto people. Most of the artists being attacked aren't forcing diversity. They're drawing the ponies as how they imagined them for FUN. Plain and simple FUN. Since there is no canon of what humanized ponies look like, there's no wrong interpretation.
In my conclusion, this whole "forced diversity" thing sounds more like people not wanting to acknowledge the existence of people/cultures/lifestyle/whatever outside of their comfort zone, let alone think of it as a beautiful thing. Unfortunately, I think this xenophobic mindset isn't limited to the series. Worse yet, some bronies act out on this insecurity (I've heard stories of female cosplayers being harassed for having differing opinions or for being overweight).
So much for "love and tolerate".
Oh, and I don't care if any rabid bronies come raging, it's just more lulz and ammo for me.
