I think this mostly works with the current order of the world, but it would also mean that e.g. a white supremacist in japan is left wing (since the current social hierarchy there if anything has japanese people above the rest - and please no one twist this into me saying japan is ultra racist).
It seems more to me that a common thread for anything considered “left” is that there should be no or very little social hierarchy, whereas right wing ideologies think there should be a very strong one (be that inherently through circumstances of your birth or merit based). In reality most places do have quite a bit of social hierarchy (and used to have more) so it coincides with wanting to change the status quo.
There’s probably something I’m forgetting that is considered left wing and loves hierarchies
What are you arguing against here? If you think you’re defending yourself then you think you’re defending yourself. If you think you’re helping the people you think you’re helping the people. Neither means the outcome will be good or the actions justified. All the person you’re responding to did was reason about Thatcher’s possible motivations.
Do you actually understand the term strawman because arguing against a strawman is exactly what you did there.
