RE: Teen Wolves
I've seen some Youtube videos about teen wolves/teen werewolves and 99% of them are basically just going through a phase that will fade away with time, however the 1% might actually be legit therian or otherkin and will awaken themselves. I think its rather offensive that most of them are trolls and will go off on anyone that dares to point some real facts out to them and end up giving real therians and otherkin a very bad reputation.
As for the goth style most of them appear to dress, that is most likely just something that goes along with their phase. But for legit therians and otherkin it could possibly apply to what their wolf looks like. For example, I tend to dress in all black because my fur was pitch black and I also just really love black and white lol.
And the collar and leash thing, Eh, I'm not really offended by collars and leashes, I actually kinda like them, but I can see how some therians would find them triggering. For the teen wolves/teen werewolves its most likely just another accessory or just a way to further show off that they think are of a canine species.
All in all, I don't mind them, but if they decide to harass, bully, or just be flat out offensive, then ill have a problem. But other than that I haven't had any problems with them.
