I'm happy to let you discuss amongst yourselves.
However, just as commentators have no right to offer blatant libel or repeat propaganda to me, you have no right to blatantly libel each other. Requests to have someone else's comment deleted will usually see a favourable response, as long as that comment is addressed to you. I don't try to rebut crazy and you don't have to either.
You can if you want, though.
