When it comes to roleplaying and wings, it kind of depends what you're roleplaying in the first place.
As there is no proof of angels, dragons, mermaids, trolls, unicornw and other creatures, they do class as unrealistic.
It's the same when you write a story, or look for books in the library.
But to contradict this a bit, you do get people who roleplay fish, birds and human etc.
They're forced to use the canine and feline models for their characters.
So I do wonder if wings really matter. It may simply be something they use as items.
But that is up to the leaders of the roleplay to decide.
If someone wants you to remove the wings to be inethe roleplay, fair enough.
But it's not necessary to call people names such as "noob" for it.
To sum this up.
I do class wings as making your character unrealistic, but it depends what you're really role playing in the first place.
It really depends on the character you are roleplaying as. If you are roleplaying as a bird, then you may be able to get away with wearing wings. But someone out there is bound to notice and call you unrealistic when really, you are using what you can. We don't have bird models, only felines and canines. I think that people should face their fears of wearing wings, if the person RPing with wings likes their character in them then they shouldn't be forced to take them off or make another character because of someone else's opinions.
Basically: It just depends on what you are roleplaying as.
