@nimh,
Because the thing is, it's easy to figure out who's right and wrong in an argument. The person with facts to back their assertions just needs to state those facts. Truth speaks for itself.
On the other hand, the person spewing bullshit will do everything possible to silence the person stating facts that they disagree with. They do this because they know they're wrong.
So if you're on the fence about an issue, ask yourself who's being silenced in this situation and not being allowed to speak. 98% of the time it's red pilled men and conservatives.
