Neither. The Humane Party does not fit neatly—or at all—into a “conservative” or “liberal” slot. The Humane Party’s positions are based on science and ethics.
For example, consider the Humane Party’s policies regarding climate. The heat-trapping properties of a greenhouse gas (e.g., methane) can be measured and have been measured. The results of these measurements are not in dispute anywhere in the global science community. The Humane Party recognizes these measurements as a matter of science and math, not as a matter of “conservative” or “liberal” ideology.
In developing policies based on these measurements, the Humane Party has paid no regard to what the “conservative” or “liberal” view might be and has afforded no consideration to what “conservatives” or “liberals” as such might prefer.
