It is rare that you have an opinion and have a 180 when thinking about it for a long time. When I was looking for additional writers two years ago, I made it a condition that they use their real name. To me hiding behind a screen of anonymity was a coward's way out. If you had something to say, say it and stand behind it. With your real name.
I had long discussion with people who do use pseudonyms. One pointed out, that a pseudonym is not really hiding. As one tends to use that fake name all the time. Lots of writers in the past had pen names. Magicians all over the world use pseudonyms to distinguish their real personality from their stage personality. Slydini and Dai Vernon come to mind.
Man is least himself when he talks in his own person. Give him a mask, and he will tell you the truth.
And that is also true. Lot's of people are pissed off by Harry Loraynes constant advertising over at the Magic Café. If you talk out loud against it, you'll get banned. So why not create fake accounts and live out your freedom of speech.
Sure the use of a pseudonym is the way to get a life as an Internet troll. But be honest: We have matured enough to spot a troll and ignore him. If this is your main concern about not using the real name, then it is a weak argument. There are plenty of reasons not to use the real name.
So I have come 180 on this, as you probably have noticed by giving that freak Barry Solayme author rights on my blog.
However I will keep using my real name, as I am a magic troll. And if I verbally slap you, I want you to know where that slap was coming from.
