That does not excuse somebody coming out and being rude and snotty to a poster who hasn't done all of that (well, not yet on this thread.)
And yes, I've been called "neocon," "statist," "warmonger," "big-government lover" and much, much worse by Paul supporters. All simply because I do not support Ron Paul.
Unfortunately, it is the sort of thing I have come to expect from the Paul crowd.
Most people who are in favor of going to war all over the world are in fact neo-cons. Paleo-conservatives generally do not like to go to war for any reason unless directly attacked by said country (or immediate knowledge of upcoming attack). This goes back a long, long way in US history from before WWI and at the start of WWII. I don’t really consider that name calling anymore than calling you calling me a libertarian is. You are right though that in general name calling does little to further a cause or the debate in general and no it’s not excusable.
