I’m failing to see how Robin violated any copyright. He linked directly to the original source. He then quoted the article on the chance that it would not be available later at the place he linked to. He never took or claimed the post as his own work, even leaving your original signature on your piece that he quoted.
Also, you are partaking in a standard argument (a version of #12). You are insulted by one person so refuse to have a discussion with anyone else - especially the ones who counter-argue your actual points - and duly end the conversation or ignore anything except the non-issues to the topic you don’t want to address. So, good day to you, too. If you’re not going to address anything questioned or countered from your argument there is actually no reason for you to remain here.
