The left represents equality, inclusiveness, freedom, justice and moralityIt's not "for whatever reasons," it's because the terms no longer apply to the real situation.
If they did, someone would be able to define them in a way that would make sense of today's politics.
But nobody can--not just here, anywhere. Meanwhile, there is a large and growing number of political phenomena which do not clearly fit into either category.
I think the question might be looked at another way: what is to be gained by retaining those terms?
The right represent inequality, exclusivity, control, elitism and immorality
