Thats the problem. "Far-left" is just a label thrown around by ideological people without hard arguments.
Core leftism is about wealth distribution and unbounded solidarity. Being only pro-LGBTQ imo does not make you a leftist and yet, look around in this thread, what is brought up to proove left leaning tendencies.
The labeling/propaganda unfortunately worked and we devolve into tribal identity politics. Thats why some people think we just passed a far-left decade.
”Far left” is the new ”communism”. ”The civil rights movement is communism.” ”Gay marriage is far left.” The labels don’t mean anything else than ”something we don’t like and you should be scared of”.
