rbutr rebuttals can absolutely be rebutted. Any page can be rebutted, so you can follow a whole multi-step debate online.

Is that what you meant?

For example, one link:http://rbutr.com/rbutr/WebsiteServlet?requestType=showLink&#... where the rebuttal is rebutted: http://rbutr.com/rbutr/WebsiteServlet?requestType=showLinksB... where the rebuttal is rebutted: http://rbutr.com/rbutr/WebsiteServlet?requestType=showLinksB...
