It’s not a mental disorder to be a far left lunatic, it’s a spiritual disorder.
The Christian Conservative side, “the far right”, tell people that their sins are bad, and they must give up those sins. A lot of people don’t want to hear that. The world tells people their sins and vices are actually virtues, to be celebrated and defended. The Democrat Party has very successfully tapped into that, and they have become the party of the spiritually broken, as they attract the types of people that reject God. For these people, the Democrat/Progressive ideology becomes their religion. One where they can make up their own reality, like killing unborn babies is a “woman’s right”, or that homosexuality is perfectly normal and acceptable, or that people can “change genders”. They are all lies, and they find themselves defending every lie on the left in order to protect the one they are personally tied to.
The Democrat party has essentially become Satanic in nature. It’s all about rejecting reality, and creating a fake reality. They’ve taken grave sins and made them virtues. Like the demonic, they absolutely detest anyone speaking the truth, because it exposes their absurdity. Charlie Kirk spoke the truth to them and they hated him for it.
This is why Christians will always be hated, persecuted, and martyred: because they speak the truth in a world of lies.
