There is a difference between trolls and people who have a different opinion.
Calling it ‘trolling’ when people have a different idea is of course the easiest way to pretend your idea is still the best, but this behaviour doesn’t result in constructive discussions of your idea.
When your first reaction to people who have other ideas about your idea is to call them ‘trolls’ you are setting up your idea for failure.
Why not try to see why other people have other views and challenge their views instead of namecalling them?
But no, instead of trying to defend your idea you call the people who want to discuss your ideas trolls.
And then instead of responding to them, you make a new thread to complain about trolls. 
What’s next? Are the people who disagree with you in this thread trolls too?
