You also don't know how biochemistry works, either. Nor are you informed about the current findings of prevailing Martian geochemistry.
You're not going to grow lichen on rocks that chemically bind water into different types of rock. You are not going to GMO plants into utilizing them, either.
Every terrestrial macroscale life form known isn't a modular organism. It's a complex, messy, interconnected thing supported & simultaneously under assault by a billions year old ecology. This ecology will never exist on Mars within the timespan of the human species, regardless of any genetic jiggery-pokery we do.

... You don't know how evolution works. Noted.

Nothing is growing on Mars due to the chemical realities of the planet. At least not for long.

Not true. We know quite a bit, actually. We know chemical composition, age, geologic conditions, tectonic patterns, solar saturation, mean temperature & radiological conditions.
And all point to Mars being a cold, dry, inhospitable deathtrap for humans. The famous red dust contains poisonous chlorate compounds, while just under a thin topsoil of hydrate minerals lurk hydrate precursors. Substances ready to take any available liquid water they encounter, & irreversibly transform it into stone.
Why is it irreversible, & why not crack the existing hydrates for their trapped water? Because it'd be extremely energy intensive, & Mars doesn't get very much energy. With roughly half the luminance, Mars gets about a quarter of the solar energy input that we'd get on Earth. While the amount of water we'd get is, again, insufficient to bulk out a breathable atmosphere, much less sustain a science outpost or Martian agriculture.

Actually, no. NASA did the matu based on current estimates, & if all the water & other greenhouse gases on Mars were melted & vaporized, it'd only supply about 6% of Earth's current thickness. Not nearly enough for sustaining life.
Then there's the hydrate problem.

The "attacks" are from organizations that pay attention to actual implementation of the technology, finding it to be nothing more than another distraction & boondoggle by the fossil fuels industry. Like ethanol or biodiesel, both of which similarly require the preservation of a robust petrochemical industry.
