Four things you never listen to Leftists about:
War and military: They hate the military with all their heart. Any attempt to seem like they are on the military's side is just in hopes to co-op it. They hate veterans. They hate war if they might get drafted or if it is in America's interests, but support wars they can endlessly grift off of while still claiming to hate war. When war is on their side it is a 'necessary disappointment' but when war is produced by non-Leftists it is immediately a war crime and leftist politicians and agents immediately start leaking data to the press and America's enemies (I repeat myself there). A war where the US must deploy troops to finalize it will be listed as a war that has been lost while the rumor the US will go boots on the ground is still just a Leftist fever dream. They will occlude the true actions of the military and a war by having a pet reporter spout lies and then quickly build on that lie. Entire wars have been lost because of Leftist pressure. America is not allowed to win a war, because that prevents the Leftist from pushing America down even further. War is an easy way to make your country proud of itself and that is not allowed to a Leftist. They routinely treat veterans with as much disrespect as possible, often while pretending 10 seconds later that they are the ones who really help veterans. No veteran should ever bother giving a Leftist the time of day. The Enemy is a better human being than a Leftist because at least the Enemy was just trying to kill you openly.
Perversion: Hippies and thus Leftists are masters of perversion. From "children are sexual beings too" to "woman's brain in a man's body", Leftists have pushed the most insane and harmful sexual ideas in the US since the 20's. Any time a leftist screams about a pedophile, it is projection and anger that the person isn't on their side, if they are a pervert, because a pervert's natural home is with morally bankrupt child molesting faggots. Hippies and Leftists have spread drugs through your community, pushed sexual abusers into every faction of life, including teaching American children and taking care of them. Leftists only protest immoral actions when their enemies can be painted (truely or falsely) with that brush. They will lambast and call for justice against someone who pinched a waitress's ass while they themselves are still in the process of sexually molesting a small child. Do not let a Leftist lecture you about anyone not a leftist being an immoral pervert. Do not bother engaging with them to argue it. They do not care. They will pretend that only their target has committed that crime and will deny that they secretly wish they had been the ones to do it.
Race relations: They hate you if you're white. They hate you more if you're black and refuse to stay on their plantation. They have been pushing anarcho-tyranny where their pets can do whatever they want and everyone else has to live in fear of their pets AND law enforcement that will punish YOU to the full extent of the law for hurting the feelings of the guy trying to murder you.
Law & Order: Leftists are natural traitors. They routinely leak military secrets. They routinely leak classified data. They want the cops disbanded in YOUR area. They want the cops to stop PROTECTING you but not PUNISHING you. They are the masters of rules for thee but not for me. They have set off bombs, tried to break into multiple government buildings when they don't get their way, including weeping and clawing outside a door trying to break in. NEVER let a Leftist lecture you about morality, law and order, or crime. Simply ignore them.
Their three greatest tricks are 'not knowing things', 'not understanding things,' and 'repeating the same phrase over and over no matter what is presented", this is often seen in camera footage.
Do not bother to engage them in honest dialogue. They do not care about honest dialogue. Dialogue is not a way to change minds, in their view. Dialogue is a way for them to perform publicly and privately that they are a Good Person(TM) and you are a Bad Person(TM). No dialogue will ever change a Leftist's mind because leftists don't know things. They repeat what they are told. There are entire sites out there that do nothing more than tell Leftists what to think and feel.
Limit your interaction with them. Any interaction merely proves their world view. Even if it does not, the plasticity of a mind that does not retain knowledge will rewrite the encounter to show they were correct and everyone clapped.
Leftists are monstrous scum who enjoy molesting children, living off of other people's labor, and yelling slogans at each other like birds.
