This does not necessarily follow.
Doubling down on becoming oil independent might have a massive price because the required investments into extraction and refining industry could also be spent on renewables.
Furthermore, we already see renewables outcompeting fossils on price/kWh, so ending up in a really inefficient sunk-cost pit is pretty likely, with all the refinery investments not even paying back their cost because a conflict now does not guarantee that fossil prices/demand will stay high.
If your intention is honest engagement with people you disagree with, you should refrain from ad-hominem attacks like this. Work with their arguments, not with their tastes or appearances.
If your intention is to ridicule them and convince yourself they are not worth discussing with, then ad-hominem is fine, but not engaging at all is better.
There is a difference between judging an opinion and judging a person. If the response had been something like "what is crazy is to think the world can just switch off its dependence on petrol suddenly", I would not have reacted either.
