I'm not sure if you intended this meaning, but it sounds like you see (your) liberal view as the ultimately right one which will inevitably triumph in the end, its just bad tactics right now. I didn't notice this until after I got back to the US after some time in an authoritarian country, and I noticed that liberals had this similar authoritarianness of being unwilling to consider the merits of the other side, a fee…
I'm willing to say that, yes, most "liberal" ideas are ultimately right, and will ultimately prevail. History has by and large been a march towards these ideals. Freedom, equal chances, some organized support isolating you from the raw&random powers of markets&nature. That believe isn't new, by the way. The first progressive would have said: "We believe these truths to be self-evident".
My understanding of how Americans use the word "liberal" is that it's an alternative way of saying "left wing". In that case history has not been a march towards left wing views, surely the fall of the USSR, the rise of Reagan and Thatcher ... it's been the opposite.
And aren't "liberals" now pitching for unequal chances? Like, HRC should be President because she's a woman, affirmative action, get women into tech funds etc?
It looks like you just picked a few things that are widely regarded as good, and labelled them liberal.
