whilst in principle i don't necessarily disagree with the sentiment of using "real" names, for some it is a matter of practicality to remain anonymous.
i guess for most people working professionally in the woodworking or building industry then it can be a complete boon with regard to getting work and networking professionally; however there are some people (myself included) that have an interest in a personal capacity however wish to remain anonymous for other reasons.
i keep total anonymity on the internet, no photos of myself or family, no blogs, no social networks etc that could ever tie to me or where i live to being identified. this is not because i am famous or even infamous in any way. i am not a bad guy up to nasty things, i am not shy nor am i looking to rant at anyone or about anything.
professionally my work has brought me into contact with people i would rather not know where to find me either on purpose or by accident.
names are arbitrary anyway, they are merely a label with which to address others. there would be no guarantee the name given would be a "real" one anyhoo.
i think respectfulness and kindness come from the individual whether their name is a given one or chosen one.
i have no problem in using a traditional given name or offering a gender, however it will not necessarily be what i was deemed to be at birth and if "forced" to do so would make one up anyway.
