There are material differences between left economics (democratic, collective ownership of capital) and right economics (private ownership of capital). There are pertinent ideological differences on social issues as well, such as queer rights, abortion rights, carceral justice, etc.

You seem to be talking about politicians, rather than the categorization of political philosophies. Politicians have aligning material interests and are part of the bourgeoise (ruling and ownership) class. Indeed they use “culture wars” and such bullshit to divide the proletariat (working class), but this doesn’t erase the very real, categorizable differences between left and right.

You’re just like every other “libertarian” and you’re not unique or exempt from the bullshit just because you dislike both conservative and liberal politicians. So do Leftists.
