If you get into an argument with a Trump cultist - which has a solid chance of being a paid Putin troll, by the way - they will downvote more quickly and in greater numbers if you provide sources.

In other words, they find it more urgent to suppress and hide your comment if you prove it.

Which basically means they know they're lying. They are simply psychopathic liars acting out of pure malevolence and hate, and the worst crime they can imagine is to prove that they are wrong. The truth means less than nothing to them. The truth is their Orwellian definition of evil.
