I have found that almost anything can be said and any argument made while following the above rules. However, if you have clearly violated one of the four list rules above, expect an e-mail from me the first time and banishment from the list the second. The Kexpat list is for individuals. Businesses may post to or monitor the list, however, they are offered no special protection against criticism by the moderator or Nextel. Stay away from controversial subjects on which anyone rarely changes their mind.
Some examples are evolution, abortion, religion, etc.
There are plenty of newsgroups and lists that cover these subjects. If you enjoy engaging in these discussions, let me know and I will point you in the direction of the proper newsgroup or list. While not forbidden, please refrain from sending HTML mail. Many subscribers can't read it. Although not required, it is requested that everyone who joins the list introduce themselves via their first message.
