@ Everyone:
Thank you SO MUCH, everybody, for your very interesting and very informative replies. I learn so much from everybody ... things I did not know and was not aware of. Many of you are very well-informed and have wide and varied experiences. It's SO EXCELLENT to read your posts, learn and understand things I never knew that well or understood that well.
@ Britney_413:
Hey, I can really appreciate how you feel, and people can sometimes really torque us and freak us out with snide and dumb comments. It's so easy to REALLY get upset and let them have it, especially when they really deserve it. When I was younger, I did that a lot!
You know, my experience is that you are basically right about all of this. I've had similar experience with the LGB component of the LGBT Community. Two of the people of utmost prominence in the LGBT Community in our city were rude, unprofessional and juvenile beyond belief and comprehension when I recently contacted them, by e-mail, in a concise, polite and non-threatening or -aggressive way offering to help them with writing and ad sales. Their comportment and demeanor where absolutely perfect examples of what not to do and how not to handle yourself if you are the LGBT Community.
These are people who REALLY should know better, but alas, they decidedly do not. 'Tis a pity. So, what's my point? Just this:
As much as possible, be the emissary of good will ... be diplomatic ... be gracious.
Oh, yeah, I understand that people like that guy you talked about are stupid, rude, a-holes, etc., etc., etc., ... fill in the blank! True, true, true! BUT! Grace, tact and dignity all the more are the order of the day in such a situation. This is so easy to say and so hard to do, but we MUST do it ... if we are to foster understanding of us and foment respect for us by the larger society.
I'm facing a situation right now as I write this where somebody has heinously and shamelessly betrayed and used me (... and I'm talking about in a criminal way! ...)(... who will way blow your minds, folks! ...), no s--t! How am I handling it? With: Grace ... tact ... dignity.
The Mahatma Ghandi ... Mother Teresa ... The Dalai Lama (Did I spell that right?) ... were premier examples of how to do this and how to win the respect of nearly everybody if not their approval. Yeah, I know: This sounds like B.S. It's not. When I was young, The Beatles had a song called "Love is All You Need." Corny as that sounds, it's the plain truth. Unfortunately, because there are so many rude, stupid, violent people in the world, WE will have to be the ones to give ... to compromise ... to back down. With some folks (... too many, in fact ...), even this will not do. They are to be avoided if and when you can possibly avoid them.
I am guessing that I'm quite a bit older than you are (understatement!), and if I've learned anything, I've learned the little lesson I'm trying to impart here.
Indeed, it's the BIGGEST lesson any of us will ever learn. Okay, I'm a dreamer, but I'm not the only one. Hmmm, seems like I've heard that somewhere before:
