One of the problems I have a lot when debating with liberals is their very sense of justice seems to be backwards. They seem to believe that something is justified only if it's surrounded by compatible circumstances, ignoring the value of something itself.
The first belief is called coherentism. The second belief is called foundationalism.
Obviously, coherentism is circular because it begs to know why something coheres in the first place. You can't have a puzzle without puzzle pieces.
A liberal response typically goes that it doesn't matter what the particular puzzle pieces are. It just matters that they fit together.
The problem, of course, is that raises the question, "How do we know what fits in the first place?"
Liberals typically claim that "what fits" spontaneously emerges among dynamic interactions between people.
Unfortunately, liberals don't seem to care that spontaneous emergence doesn't necessarily yield compatible solutions. It's at this point that we see that liberals are tyrants. They don't care if slim minorities fall through the cracks of society. They just care about the big picture as long as the minority is too insignificant to be bothered. This is why liberals love free speech and democracy - they love how people can be intimidated from appeals to absurdity, and they love to employ mob justice in forsakening independents who don't conform. To boot, they can claim that they tried by giving people a shot to fit in, so they don't have anymore due diligence to be responsible for.
Ironically, this appeal to democratic popular sovereignty is how liberals become elitists. For example, lets say liberals claim that 1% of society is a tolerable insignificant minority that can be allowed to fall through the cracks for any particular issue. Given a society which has multiple issues...
99% * 99% = 98%
98% * 99% = 97%
97% * 99% = 96%
If society multiplies 69 issues, this leads to only 50% of society being compatible across the board.
If society multiplies 229 issues, this leads to only 10% of society being compatible across the board.
If society multiplies 458 issues, this leads to 1% of society being compatible across the board.
Issues don't have to be big matters here. We don't have to be talking about abortion, gay marriage, gun rights, income equality, environmental protection, or labor reform.
They can be simple things. Things like, "When should people be allowed to play music into the night?" or "Where should a road be built?" or "Should we teach school curriculum this way or that way?"
The point is liberal coherentism doesn't actually include all people. It just includes most people, and when "most people" gets repeated over and over, this leads to a very small minority actually being compatible with what society stands for.
It also leads to social tyranny because those who are more compatible over more issues are treated as superior to those who are less compatible.
