Quoting entire paragraphs may not be sufficient to provide proper context, and especially if being willfully misinterpreted, can be potentially harmful.
But well intentioned quotes, immediately under a post providing them in their full context - which is the case in my post you replied to? I'm hard pressed to see that as distorting your meaning and harming discourse. If you have specific grievances as to how I have, please state them. If my understanding is distorted, there is harm to discourse regardless of whether or not it's visible in the form of distorted quotes.
The many questions I'm asking are my attempts at understanding the context of your statements, to avoid such distortions. The couple that you've answered have clarified some things. A couple more have been mooted by indirect responses. Many others are still relevant and unanswered.
Even now, I'm a bit unsure if you're saying that I've done harm, in the specific post I made that you were responding to - or if you're making vague generalizations again, this time about sentence level quoting on the internet in general. I'm assuming the former for now - but please correct me if I'm wrong. I would ask, but that's clearly not working out for me.
