Look at 2678 and 2679 together. They are moving the conversation away from the issues and towards a criticism of the Freeper himself. That is “making it personal.”
With regard to 2678, I’m not sure how to respond to a style of argument that says, “You should listen to what we say because we are the Tiger Woods of X,” when X is the subject under discussion, without addressing whether the messenger has any valid personal claim to the said Tiger Woods-like qualities. The fallacious reasoning seems to beg a personal response. I will try in the future to simply point out the fallacious reasoning without resorting to sarcasm or discussion of personal qualities, even if the poster seems to be inviting them.
