There are 3 evolutionary traits throughout the eons which delineate various animals on the planet.
1.) Instinct - this is hardwired into a lifeforms biology/DNA. In a plant, it is what makes the plant grow in a certain way. In an animal, it is what makes them reproduce and survive to pass on their genes.
2.) Emotion - This is an evolution of the biology to include an additional set of chemicals into the organism which allows it's species to operate collectively. Only mammals possess this trait and it hinges on emotion. Elephants, wolves, dolphins, dogs all use emotion to communicate. It is also the reason why humans can communicate with mammals, and not reptiles, or bugs. Example: A dog tilts it's head, cocks it's ears, and pulls it's eyebrows up. The human knows that the dog is paying attention and "thinking". The dog is not "thinking", the dog is feeling, but the dog is questioning and looking for an answer. So, there is emotive communication.
3.) Thought - The ability to entertain concepts and ideas which the organism has no frame of reference for; imagination. This is the trait which sets humans apart from the animal kingdom. It is what allows humans to look at problems, and come up with solutions. In order to generate a solution, the human has to first imagine an answer which does not currently exist to be able to create the solution.
How is this related to liberal logic.
Because of #2 - emotive language, the progressive narrative has made it popular to de-evolve back into simply being mammals. Through their popularization of emotive language and "I feel language", progressives have started a war on thought. It has become culturally accepted to say "thinking", and mean "feeling".
Person 1: "I think guns should be banned."
Person 2: "Why?"
Person 1: "Because their scary"
Person 2: "Do you have any facts/figures/arguments/reason to back up your feeling?"
Person 1: "REASONS"
We've all heard the argument. This same theory can be applied to every hot topic of today. Try it, let me know where it breaks down.
Thus, progressives aren't human, they are apes, by choice.
