Conservative lost its meaning, now we just say "republican", with a lowercase r. Edit- Do conservatives make new government walls, tariffs, new taxes/tax structures, new tax credits, new gun regulations? I even heard an interesting idea, why are conservatives destroying the environment, they shouldn't want the environment to change if they are conservative. Anyway, the 2020s breed of "conservatives" would be seen as liberals in the eyes of 2000s or 1980s "conservatives".
