Other respondents in a discussion have the right to examine any source you quote. That's why it is important to provide citations for your quotes. If the second and third paragraphs above are located at an Internet link, simply provide that link. Other respondents may, or may not, wish to examine that source first hand. Were you to actually publish what you quote without providing any attribution, it's called intellectual property theft. Maybe not as serious a no-no on an Internet forum, I doubt the author will come calling for you, but cherry picking in service to confirmation bias is not a position of strength, usually. Bottom line, if I want to examine where you copied and pasted your quoted passages, I have to go digging for it. But, in a discussion, you are obligated to provide that citation for us. At the very least, you can copy and paste the link itself, the source, the citation, the original credit for the quotes. You are always fully entitled to your position, but people are going to keep pointing out plagiarism until you cease committing plagiarism. I should think, since it is so very easy to correct that shortcoming, that you would just do so. In the above instance, by providing quotation marks, you are at least broadcasting "hey guys, these are not my words". That's a start, but without a link, you are making it difficult for any other respondent to examine your source. And certainly there is nothing to fear in providing that link.
