I don't want to give the entirety of your post a short answer (or your other post either) but I will start with this
"is this a responsibility (implied: the role of the dominants who use this site, to police the behavior of the submissives that use this site) that you are even willing to acknowledge?"
For me, I never was trained, and I don't see anyone else's behavior (except my him) as a reflection of my pride or honor. I do understand where you are coming from, but I am not ashamed that I am totally different than you, in how I came to be here and in how I relate to the other users on this board.
I don't own have any dominion over the submissive on this board. I don't want it. They owe me nothing. Their choice to submit is not mine. Also, my choice to dominate is not theirs. This is actually important to me: when a sub expresses overly courtly/polite mannerisms, especially replete with A/all that crazy C/capitalization, it is really frustrating- it is a very disingenuous.
I assume that most of the people who use this board, whatever their orientation, commitment, and level of experience, are here for the same reason as I am- to learn, to talk to other people, and to enjoy being accepted. I really try not to label or judge others- no matter if I personally think they are bratty or snobby or anything else.
"what are you going to do in the future to meet that responsibility head on and do it true justice?"
I suppose the best answer would be that I will redouble my efforts to be a better person. I will also (and this is not a smear against this site, at all) spend more time looking at other sites and other sources or knowledge. THere are many lost souls in this world, and the more knowledge I have to share, the better. TO quote the Unitarian-Universalist doxology "service is our prayer". I am not a UU, but I agree that actions are the only true method of expression.
Ironically, I am starting the orientation process of a formal mentorship program, tomorrow. The motto is "facta non verba". I do not regret in any way that I come to where I am in a informal way, but I am happy to be able to participate in a forum where I will learn from more experienced and more formal dominants than I.
