You're just talking about differences between liberals within liberalism. Obviously that happens, which is why I asked what positions of American liberals go against liberal principles.
Yes, I was describing the obvious differences and conflicts between social liberals and classical liberals.
Social liberals and classical liberals will -most of the time- still be closer to each other than they are to fascists, communists, nationalists, socialists, neo-Nazis, anarchists etc
But at the same time very different ideas on issues which are seen as important by either side, can lead to a quite hostile atmosphere. I don't really see how big-tent liberalism can be seen as one group other than in extreme situations, like when they're collectively threatened by nationalists, communists etc
For example, a European classical-liberal party could (and in some cases does) actively work against the "right" to various social welfare benefits or many forms of workers' rights while social-liberals in the US might see the exact opposite as one of their top priorities.
From my experience, if you argue for a classical-liberal position, let's simply say here on Sherdog, you're often seen as 'the enemy' by social liberals and vice versa.
I don't claim to be a classical liberal btw, I'm just saying I had multiple discussion where a classical liberal could have made the exact same argument without violating principles of classical liberalism.
The fact that you don't advocate unlimited state surveillance, fascism, the drug on wars, largely unprovoked military interventions or that social liberals also acknowledge the superiority of a market-based society and other things doesn't really change that. And to be honest, I don't even think that's an accusation, I think it's quite reasonable. But I intentionally said 'seen as an enemy' because I don't feel like it's a discussion that typically plays out like 'ok I see your point, but wouldn't it be better... oh no? well, ok but we can agree on...',
instead, both sides are often convinced that their opponent's views are inherently
immoral and therefore make him an evil person.
