I'm sorry, but that's not the right approach. The anon's concerns are valid. Consensus should decide on whether the content he is removing belongs in the articles or not, and (a) it takes more than two to build consensus and (b) reverting one another is no use. If you keep adding back information you think is relevant, and he keeps removing it, nobody wins—least of all the people who are reading these articles on a daily basis and coming to Wikipedia for information—and you'll just keep going at each other in Talk pages.  (t·c)
