Actually, what you post are other people's words and the fruits of other people's labors. Even with the quotes where you give credit to the original author, you fail to give credit to the people who compiled them and inserted them in lengthy essays.
But your biggest problem is not plagiarism, but you lack of judgement. You are plagiarizing from loons who think the frog in a blendor is a good example of a failed prediction of evolution.
In the entire history of these threads -- all the way from 1720 to "circles are not elipses," this is the stupidest.
"Boo hoo! Your posting from textbooks pdf files and clips from other web sites! WAHHHH!"
That is what you are saying. You can't counter the evidence, so you attack the person who presents it to get off the subject.
That's weak.
