Apparently Bronies ruin stuff by being friendly.
No... No, no no no.
Bronies ruin stuff because they enter things fully expecting everyone to accept what they like as they rub it in everyone's faces. Most of them simply wont shut up.
Yes there are exceptions, yes they are not all stupid this way, but the majority of them are and this is why I will never like the people or the actions of Bronies. They need to learn that not everyone is 'on board' with this 'love train' that is My Little Pony.
