The first quote is in bad taste, though the context is not as bad, and the comment as a whole lead to a pretty interesting exchange. I see nothing wrong with the second quote, it is not intentionally made to offend, it's part of a reasonable argument. Even if you disagree, or the author is not as informed as you on the issue - that doesn't mean they should not be saying what they did. The purpose of the comments is to discuss things, not to display your ideological allegiances or be right about everything.
