From your link: "In Europe and North America, the establishment of social liberalism (often called simply liberalism in the United States) became a key component in expanding the welfare state."
Idk, that seems compatible with most of the left-of-center spectrum, and certainly not something you would find a libertarian or conservative supporting. I can see how it's not compatible with auth-left positions, though.
Perhaps you're referring to neoliberalism, which, in my understanding, dropped all the social welfare stuff in favor of corporate welfare. In that case, I can understand how that term could be used as an insult.
In my eyes liberalism != neoliberalism. I consider myself liberal, and I despise neoliberal policies.
I must have higher standards for what constitutes proof than you have.
It's not that I disagree with your point or agree with the post you were replying to. I just don't see how your image supports or refutes any of it.
