The argument, from when there even is one, is pretty pointless as well. Essentially, it boils down to one of two things. Either redefining terms or using a different base.
One of the arguments went on for a long time, talking about how base 2 has 2=10. The problem with this is that you would have to get into some pretty weird fractions, possibly irrational numbers, in order to find a base that would force 4=5. It's not as simple as base eight either, because in base 12, numbers still equal themselves, 6=6.
Another argument was essentially that numbers are symbols and symbols are arbitrary (one actually tried to say that 2 was a variable) and so can be redefined at will.
The funniest part of all this is that it got started by an anti-woke guy using it to taunt them, and then they all came out to defend his attack automatically. They really have no idea how bad this kind of knee-jerk response makes them look. I know a lot of people have never heard of things like the 1619 project or critical theory, but even the poorest educated individuals in the US can at least count on their fingers.
