When people tend to think of trolls, they think of people who either disagree with them or just happens to have a bit of an unpopular opinion. That's just having different opinions. A troll by definition are people who intended to deliberately piss people off through the internet, receiving an angry response from them for shits and giggles.
Now, internet flamers on the other hand, are people who not only hold different viewpoints from others and dislike and disrespect other people's beliefs, they also maliciously attack others with those different opinions out of the intention of starting a senseless, heated argument/debate.

Agreed, actually. People say the guys here who says "lol drown in a lake" are trolls, but really they are just asshats. Trolls generally make a point. You can only rile up people if you attack something they will be eager to defend. That is why religious topics tend to waltz down the roadway to verbal hell.1
