Less than you would expect, this looks like it's a good, balanced synopsis if you're interested however you're not wrong about it being a problem, and pointing out the PR/gaslighting that surrounds the issue.

Also it's worth noting that SpaceX is using LOX-Kerosone because it's "cheaper" than options which pollute much less (namely LH2-LOX) because the cost of the kerosene is "externalized" and you are correct that something like appropriate taxing could start to fix that issue and force them to make better decisions...
