It seems you are fundamentally misunderstanding. I'll try in a few bullet points, that might make it easier for you.

1. Social justice on social media is now the primary target for multiple successful right wing politicians. Earlier moments, like gay marriage, tended to be suplementary issues whereas now they are more or less the entire focus.

2. In America at least, an overwhelming majority of people support climate change action, gun control, universal healthcare etc.

3. Despite that broad support on most progressive issues, left wing politicians are losing winnable elections.

4. The right wing policies that come about as a result of their successful anti woke campaigns have disastrous climate effects.

5. Climate change will disproportionately affect the most vulnerable people on Earth.

I hope that helps make things a bit more clear for you!

Edit: Actually, your car comparison, while pretty unrelated to any point I'm making is kind of useful here. Much like cars, social justice comes with a cost. Insisting that there is no cost is just as silly as when climate change deniers argue that cars don't have an impact or that we all need them anyway so what are we going to do etc. Social justice, while fun (who doesn't love a chance to be snarky on the internet in defense of the oppressed without any work or sacrifice?!?) is coming at a cost which we refuse to acknowledge.
