Look at the words in the definition of a troll:
   ➛ intentionally
   ➛ amusement
   ➛ inflammatory
   ➛ offensive
   ➛ provocative
   ➛ disruptive

'Intentionally' and 'amusement' are accusatory speaking to the motivation of the speaker.   

'Inflammatory', 'offensive', 'provocative' and 'disruptive' speak to how the hearer reacts to a statement.   

Notice that all of the words in the definition of troll are subjective words and not objective.   

Truth is objective.   Truth is directly connected with love as is demonstrated in the life of Christ Jesus.   

But Jesus was labelled a liar, a pretender, a child of Satan by those who were offended, provoked, enraged and divided by what He said.   

Was Jesus a troll?   Absolutely not.   

Jesus spoke the Truth out of love demonstrating that love through His sacrificial death and resurrection.   

But Jesus was put to death by those who were 'offended, provoked, enraged and divided' by what He said.   

Why was He put to death?   To shut Him up.   

So, as we look at the power of words we need to recognize that truth and what we believe may in fact be two different things.   

As a matter of fact, we are commanded by Christ Jesus to preach the Gospel.   

Though the Gospel is good news, it 'offends, provokes, enrages and divides' the unbeliever.   

Should the Gospel be suppressed because unbelievers react so to it?   

Jesus said 'You will know the Truth and it will make you free'.   

Without the Truth we are in bondage.   

What is Truth?   

For most people it is what they choose to believe.   
   ➛ But Truth is fact, not opinion.   
   ➛ Truth is reality, not delusion.   

Who has the Truth?   

That is a matter of opinion.   

And so we get to the error in identifying a person as a troll or a comment as trolling.   
   ➛ we do not know the intent of the speaker
   ➛ we react emotionally to what is said

We must always allow dissenters to speak because our characterization of them may be wrong.   

Freedom Of Speech has consequences.   Lies, deception, misinformation and disinformation will no doubt manifest from that freedom.   

But the alternative is that a select few will subjectively determine what is true and therefore, what should be allowed to be spoken or written.   

This is fascism.
