Trolling makes people angry.
Bullying makes people sad.

Edit:
I do absolutely not agree that any of both can happen without intent. That's a confused concept. Let's say I say something offensive out of some form of ignorance. There is, depending on the outcome, excusable and non-excusable ignorance. However, It's miles from a planed attack. If there is no intention to cause harm, I was trying to make a constructive contribution. The act of bullying (and trolling) thrives on dis-empowering the victim. Unintentional offensive speech does not do that.
In short you give misplaced credit to, or place blame on idiots if you call them trolls and bullies.

In an example:
You are wondering in the OP: Am I actually an involuntary troll/bully, because of saying stupid stuff?
Answer: No you aren't. You are just (sorry to say so and no saying it in any ill will or scope outside the thread and matter at hand) being a persistent idiot. You see, a lot of people arrive at the same worry as you do, mainly because of innocent naivety. I was wondering that too once. It's much easier to draw the line when observing someone beside yourself anyways.
However, the line between saying something dumb and saying something in ill fate is a wide canyon indeed.

bullying is personal insults, trolling is usualy making statements like "wow could u imagine zelda beeing a girl?!"
