still, proves mlp needs to go
It's a reminder how angry people can get over the silliest little things. Most of those anti brony types seem to think they're being smothered with ponies daily, when the truth is all the bronies are in one spot and if just one strays from the pack and dares to mention My Little Pony anywhere outside the collective they are shunned and burned.
I'm pretty sure that print pack was the first and only MLP related add-on ever to be submitted to RTB, and it still got shot down.
Maybe Ephi really wanted to "prevent controversy" but judging by his wording I think he just really hates ponies. And by rejecting the add-on for "no MLP stuff" he started more controversy than just accepting it would have created.
