Edge, I see what you're getting at and I feel ticked off because I empathize completely, that's how people are with me irl. But anyway, it's just a fact of life that fangirls like to take anything and everything and make it...cute. Chibi is the word for it or something, I dunno. But unfortunately, Thor and The Avengers came out recently with sequels on the way, so Loki has been thrust into the spotlight of their tumblr-centered lives and may remain there for quite some time. I don't think it's out of disrespect- in a way, that is how they show their respect, paying homage to the figure through art. They just interpret it in a way we don't see as giving proper acknowledgement to the nature of Loki himself. But oh well, kids will be kids.
Speaking of kids, you should've seen Comic Con last year- there were countless Kid Lokis running around, my friend was one of them but actually admires his personality and history, not just the cinematic portraying from the recent movies. But it was pretty crazy. Did see some pretty awesome costumes there. Anyways, off to get my hair cut short in the back too. Hopefully they won't automatically gender me as female, my mom gave them a gender-neutral nickname.
