Looking at the conversation, he either has some severe mental issues (and I'm saying that quite literally, the way he talks is not the way that even incredibly hateful people talk) or he is a very malicious troll

Either way, I approve of this course of action. Warn those, regardless of where they live or if they are cosplayers or not, and do not respond to him in any way, shape, or form.

He has stated that the Furry fandom is next.
I don't want someone like this in this fandom, we have enough problem furs but he will more then likely cause irreparable damage to us. all.

Wow. just... is it ok to say this guy needs to swing from a tree? Seriously, he doesn't deserve another breath!

Holy Hell that's creepy.

This is crazy... What has gone wrong with people O.o

Woah nelly. This has to stop.

I've seen this on FB a while back... this guy is mentally just plain fucked up :/
