Sure most. But you don’t worry about most, you worry about the one.
From what you have shared, and the very, very little I understand, there is no increased copyright risk by posting full text to Free Republic after you posted it to the blog.
Beyond of course that more people saw it and that increases the likelyhood of someone lifting it, but more people was the goal in posting any of it here in the first place.
Do you think I missed something or underestimated it?
There is not much risk to posting the full text here - most people are honest and decent. You just learn to be careful and very cautious on line with your writing.
It’s one of those graded things - If someone rips me off, I get PO’d. If someone takes what I wrote and uses it as a springboard for approval/rebuttal - I am pleased as punch.
