He turned a light discussion into a debate on the silliest subject possible. The thread before his entrance was what you expected from a MLP thread. Related images posted, people admitting why they liked the show with legit reasoning while others couldn't understand. Then of course the first post he makes resembles activism. An argument, citations, proof and was hilariously Jehovah's witness-like. He came searching for a debate and when I made a joke by contrasting his large post on a topic not worth while, he jumped in it.
Pinning it on Pyro is like saying you should blame him for responding to an invitation. Activism will bring in serious debate, and it's comical that it was about cartoon ponies. But hey, some people love their ponies.
