"People who just come here to lie" is flamewar/battle language. So is "push back on people", in fact. What I've noticed is that when internet commenters use such phrases, they're coming across as far more aggressive than they think they are. Everyone feels like they're just playing defense while others are committing outrages.
That kind of thing just inflames the problem further and take us into deeper circles of hell. You can respectfully provide correct information without doing that. Your arguments will be more effective too.
