Let's be real here. You're defending the use a cape in everyday wear. Nobody on terra firma wears those anymore, except for...well...you. To discuss this with any sort realism is ridiculous. I don't know how anyone can look at the picture you posted and take you seriously. If you're cruising around the park, or downtown, please take pictures of any and all males wearing a cape and post them here for proof, because I've never seen anyone wearing them outside of it being part of a costume.
It's not that the members here aren't "gentlemen", it's your lack of grasp on the reality that you look ridiculous in a freaking purple cape. Enough of this absurdity and let's move on to people wearing men's wear and not articles out of a Men of Hogwart's Calendar.
