In that case, I strongly suggest you take a defensive driving course. It will help you learn the best way to adjust your driving to be safest in the presence of other drivers.
And, yes, if someone has parked themself in the passing lane, people desiring to go past them will take any opportunity presented to get around them, even if that means you've forced them to take the unsafe option of passing on the right instead of on the left. If people have room to pass you on the right, there is no reason for you to sit in the left lane, because it implies that the right lane is moving sufficiently faster and has enough space between cars that you could have moved over without having to slow down.
It's the same rules applied to bicycles and pedestrians sharing a path. If a bicycle has to weave around pedestrians all over the place, there's more chance that someone is going to get hurt. If instead the pedestrians, who are moving slower, stay to the right, the bicycle rider always knows they can safely go to the left. When people just maintaining a speed stay in the left lane when they belong in the right, it adds a lot more guessing instead of always having the same direction be the path that's open to maneuver out of the way. If someone else in the right lane is moving slower than you, then that is the time when you can move to the left, overtake them, then move back to the right. Once in a while, that does mean someone who wants to fly ends up on the bumper of someone who is just passing someone incredibly slow but not flying, but a quick check in the mirror before pulling out will usually prevent that...just let the faster vehicle overtake both of you and then pull out behind them, overtake the slower vehicle, and return to the right lane again.
If you are going the same speed or slower than someone in the right lane, there is no reason you can't pull back in behind them in the right lane and let someone who wants to pass get around. Safe driving includes awareness of everything around you, not tunnel vision straight ahead. Every driver's manual I've ever read (and I've lived in several states and have read the driver's manuals in each of them to learn any variations in the laws) tells you that if someone is tailgating you (interpret as driving too close for comfort), the best thing to do is move to the right and let them pass.
Sure, you can blame them and collect the damages from them if you get in an accident from them rear-ending you, but the whole point of driving safely is to avoid those accidents in the first place, not figure out who to assign blame to after the fact. If someone else around you is driving unsafely, rather than being stubborn about not changing a thing and blaming them for the accident, it's much better to just get out of the way and avoid the accident entirely.
