They’re just nonexhaustive ways of describing ideologies according to considerations that don’t necessarily matter to you. The left–right spectrum originated from seating arrangements of the revolutionary French national assembly where the right favored conserving the traditional rule of church & feudal hierarchy and the left favored radical liberation from traditional hierarchies toward egalitarian rule, hence conservative right & liberal left. Alignment between social hierarchy & equality is not necessarily as relevant today or our top consideration.

Each of us can choose more relevant considerations to evaluate ideologies. I personally consider unrestricted authority incredibly dangerous, so above all other considerations I prioritize the restriction of authority to protect fundamental liberties. While the pursuit of equality is good, any ideology that does so without limiting authority to protect fundamental liberties is entirely illegitimate & immoral to me. The ends do not justify the means.

I’d argue that’s the main problem with tankies: immoral contempt for fundamental liberties.
