I always find the idea of a troll a bit silly. There are loads of people who genuinely have the views they post and are opinionated people.
I don't think many people lie for attention.
often when I've seen someone being called a troll it's because they have a controversial view and it makes people happier to believe they are a troll than have to argue with someone with genuine beliefs.
There's been a few threads where I've not believe certain aspects and on those threads I just don't reply.
