Yes, I support otherkins as long as they are level headed enough.
For those who don't know what an otherkin is. They are people who believe they have a connection or affinity to a creature that has not lived on earth. They might believe they have a spirit of another creature that has not lived on earth. These creatures might include dragons, gryphons, angels, vampires, demons, etc.
Please note that this belief is not a religion. However, since they are both beliefs, I will be making the comparison. What I consider to be a sane otherkin is someone who doesn't go like "fauk u I'm a dragon!" or something like that. Somebody who doesn't flip out because somebody doesn't believe they are a dragon on the inside. Just somebody who takes the belief very casually and understands not to state it as a fact. Just like religion being an otherkin should not give you the right to be an asshole.
I'm also highly against otherkins who deny their own humanity. Saying humans are weak and evil and hating on their own race. I don't mind if you believe you are an "insert non-exsistant creature here" but don't go off and say that you are better then anyone else because of it. You are physically a human and you should be proud of it.
Now, before you say anything like otherkins are cooked up and crazy, dragons don't exists and such. Well, just like religion it is only a belief. I still find it kind of silly to believe that there is a higher power watching over us that we just made up (just how we made up our mythical creatures) but we still believe in it just how otherkins believe they have the soul/spirit of an otherworldly creature. I guess what I am saying there is that we shouldn't bash on any type of belief, but we shouldn't shove beliefs down another person's throat.
I for one do like sharing my beliefs as a wolf therian, but I don't deny that I am a human nor do I say anything to others who don't believe me.
