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.
