Are you on Stormbluff Isle? You weren't by chance talking about this in map chat, and saying that ArenaNet should not let people kill non-combatants, were you? If not, then sorry, but someone in WvW last night was a saying a lot of the same things as you in map chat. If so, then sorry if I came off a bit condescending in my response to you.
Anyway, I have seen this complaint a few times before, and while I get that a pure PVE player having to play a PVP mode is less than optimal, trying to get it out of the way all at once is only going to make it more frustrating. Don't try to get all of WvW completion at once, and don't even try to get 100% on any map at one time.
Jump into a borderlands, and look at what points your server owns, and see if there are any POIs, vistas, and skillpoints in and around those points. After you get all of those, look to see if your server is in the process of taking any other points that have POIs/vistas you need, and if so, help them claim the point so you can get access to them. Never run off on your own into enemy territory trying to chase these things, it will only leave you with an expensive repair bill. Once you have gotten all of the easily claimed points, move on to the next map, until you have gotten everything easy in all 3 borderlands and eternal battlegrounds. Then, just leave WvW (unless you want to actually try it out, which I would definitely recommend), and come back next week when there is a new matchup, and hopefully your server is in a different position on the maps. The only point that will be difficult is Stonemist Castle, which actually will require your server to be good enough to capture it. By doing this, you can save yourself tons of time and frustration, even if you won't be able to get that 100% right away.
