While I agree it wasn't exactly woke, Alyx was most definitely a "you go girl" character at the core.
I think Alyx being a generic Action girl with the hots for Gordon is more of a function of him being a Marty Stu, as well as the story-telling of HL2 being somewhat sloppy.
The story of HL1 is pretty simple. It's more-or-less a retelling of the story of
DOOM, but with (at the time) more advanced graphics, along with integrated story-telling and world-building built into the game instead of the manual. You are humble science man employed at
Area 51 Black Mesa, but an experiment goes wrong and now aliens have invaded the facility. Pretty soon, the military arrives to kill the science team, so now it's a race to survive the whole disaster, eventually culminating in traveling to an alien world, beating a big-bad alien, and finally a lizard-man in a suit comes along to tuck Gordon in for bed.
In HL2, however, Gordon is treated not like an everyman, but instead some kind of messianic figure. Why? What did Gordon do to earn such a reputation? Survive Black Mesa? So did a lot of other people, considering we meet several of our former coworkers. Defeat the Nihilanth? All that did was allow the Combine to invade the Earth. Gordon was at the epicenter of not one, but
two incidents that irrevocably made life on Earth a living hell, and everyone got to suffer for it while he got to take a big fat space nap for twenty years. Shouldn't people dislike or distrust Gordon because of that? Wouldn't it have been more interesting if Gordon had to
earn the respect of his fellow rebels? Instead, everyone drops to their knees in hopes of sucking Gordon's cock, the random bludgeoning object you used for all of two minutes before you got a gun is treated with the same degree of reverence as The Master Sword, and the only guy who actually dislikes Gordon does so for comically petty reasons (Gordon ruined his casserole).
So yeah, Alyx being shallow waifu bait makes perfect sense, but it's far from the only flaw of that game's story. Gordon is smart, badass, everyone worships him for no discernable reason, and a woman who has never met him before immediately falls in love with him. HL2 is, in a nutshell, a teenage boy's power fantasy. But at the very least, it doesn't try to be anything more than that.
However, if you think the reason Alyx's parents are black male/Asian female, the least common kind of human pairing there is, and she sidelined the stale pale male as the series died out, was unrelated to libtard race-fetishism, you're naive.
I'm pretty certain the motivating factor behind Alyx being mixed-race is the fact that
her voice actress is, and since Eli is based off the black scientist model from the first game, it would only make sense that Eli would need to have an Asian wife.
Besides, the 2000's was a much more innocent time, as far as race relations were concerned. Those of us who grew up in the 80's, 90's or 2000's will remember being taught that race didn't matter, treat people equally, character content over skin color, etc. The only people who would've cared that there were minorities and mixed-race couples in their video games back then were the hardcore racists. It wasn't until the rise of Social Justice cultists in the 2010's that people started to hyper-fixate on race, with writers getting replaced by grifters who demanded that all fiction must bend to their ideology. And since these grifters can't write characters to save their lives,
of course their minority characters suck ass.
So I have to disagree with the notion that Alyx was motivated by race fetishism. People were a lot more "live-and-let-live" about race in 2004, being far more egalitarian and "anti-racist" than the keyboard warriors of today lurking on Reddit and Twitter.
