None needed !!
Passionate discussions happen in families, at the best of clubs, amoungst strangers in bars,etc. Why would the Internet be different? The key is knowing when to stop, take a deep breath, recognize that not responding further DOES NOT mean the other guy won and taking a break. Remember that many more folks read posts than participate and most can sort the wheat from the chaff.

PS: Don't put all your eggs in one basket --- here is my other hobby
www.m38jeepproject.com. This other club I belong too uses their vehicles to transport veterans around to various events throughout the year - a really fine bunch of folks.
