For the libertarians, it's "small government", which they argue leads to, "you should be allowed to do whatever you want as long as you aren't harming others". This justifies their stance on weed, gun control, immigration, wars, healthcare and other issues. They are pro weed, anti gun control, anti ICE, anti war, and anti Medicare for all (because all of these beliefs are consistent with, "you should be allowed to do whatever you want as long as you aren't harming others".
For leftists, it's "anti pain" (even if democrats don't realize this). This justifies their stance on weed, gun control, immigration, wars, healthcare and other issues. They are pro weed, pro gun control, anti ICE, anti war (at least when America does it; but sending foreign aid to Ukraine helps reduce their pain), and pro Medicare for all (because all of these beliefs are consistent with, "we should minimize pain".
The conservatives have no consistent ethos.
They stand for, "small government" unless it's immigration, the police, or military spending (strangely enough, conservatives want a higher military budget while not funding Ukraine's military even though America's military is almost exclusively for other country's goals if they are allies with the US), or for LGBT freedoms.
They stand for, "life" while being against Medicare for all, gun control, or an open border policy (which saves lives).
They stand for, "American tradition in 1980" unless it's Roe V Wade (an American tradition for 50 years). No matter what year conservatives think is the ideal year to base American policy off of, there will be SOME reality present in that year that conservatives will be opposed too. Any time before 1980 in the US had very high income taxes (unless the time was early enough to where segregation or slavery was reality, which conservatives SHOULD oppose). So no time period before 1980 has conservative ideals 100%. After 1973 (but before 2022), Roe V Wade was the law (and conservatives don't like Roe V Wade). Since all time is either after 1973 or before 1980 (or both), conservatives don't consistently stand for American tradition.
They stand for, "Chirstian tradition", which is code for, "Bible law" or, "Theocracy". The bible advocates open borders nearly all times immigrants are mentioned (What Does the Bible Say About Immigration? (openbible.info) contains dozens of pro open border bible quotes). The bible also advocates that loving money/capitalism is bad (What Does the Bible Say About Wealth? (openbible.info)). The bible also has some anti gay quotes (25 Bible Verses about Homosexuality - What Does Scripture Say? (biblestudytools.com)). The bible says that people that have gay sex should be put to death (Leviticus 20:13). I think ALL of these positions (except immigration) are horrible positions and the conservatives believe that at least SOME of these positions are horrible positions. But if conservatives were consistently pro bible in their policies, I would agree with basically none of it, but at least I can respect it (like I only agree with democrats about 47% of the time, but at least I RESPECT their ideology).
They stand for, "Everything Trump says, I support" unless it comes to Trump telling his followers to get boosted against COVID. The vast majority of Trump supporters aren't boosted (and I think this is fine since I don't like vaccine mandates). But then don't act like Trump is so smart that you agree with everything he says, because he told you to get boosted and you claimed he was a sell out.
So I will tag some conservatives and ask them to define what their party consistently stands for.
