Basically every legitimate issue about which the Left feigns concern is, ultimately, a race issue.
Environmentalism?
Non-Whites are terrible for the environment.
Conservationism?
Non-Whites destroy native flora and fauna.
Mass transit?
No one wants to take it because of the non-Whites.
Healthcare?
We cannot fund it because of all the non-Whites.
Crime rate?
Non-Whites commit virtually all of the violent crime.
The list is almost endless. If we address the race issue, then we can fix everything else with relatively trivial ease.
