Plautus,
1. I figured out today why your posts were being "held for moderation". It's because you've been e-mailing them to the following addresses:
English@mail.wikimedia.org; Wikipedia@mail.wikimedia.org
Please use wikien-l@Wikipedia.org instead.
2. If there's a choice between preserving context and /quoting someone out of context/ I'm sure you know which is the better choice. But you can also simply add your comments at the end of the talk page. Like, "I think this article should mention beanbag chairs more prominently!" Why bother to quote others at all, if it's bringing trouble you way?
3. No one has a "right to instantly revert" -- with the possible of exception of the edits of a hard-banned user. Try to avoid tit-for-tat thinking: it won't get you anywhere.
4. You wrote, "Having to continually and constantly defend each and every single edit, no matter how trivial, is really tiresome." If this has been your experience lately, why not try something that has always worked for me? Take some time to think about how other contributors might view your proposed edit; then word it so that they would be unlikely to object to it. It's not easy to work this way, but it pays off in the long run.
Best wishes,
Ed Poor, aka Uncle Ed
