Liberal in most of the rest of the world usually means something similar to "neoliberal" which is usually thought of as a moderate or conservative ideology.
When you say liberal, do you mean it in the way it's used in the US (a stand-in for "leftist") or the way it's used in the rest of the world?
This is a recent development. When gay marriage was less popular among voters a couple decades ago, "conservative" meant "neoconservatism", which was exactly the same as neoliberalism, but without the LGBT+.
(I hope that I have now successfully offended every political ideology that claims to have centuries of philosophical backing behind it.)
