With climate change, one doesn’t have to deny the science at all to hold a position that the optimal policy choice should be to do nothing, or to wait several decades before taking action. The science predicts some real but finite amount of harm in the future from global warming. Mitigations would also be very painful, eg carbon taxes that make air travel unaffordable to all but the very wealthy.
And in terms of healthcare, everyone agrees the system is broken. In fact, one of Trump’s biggest campaign promises was to fix the US healthcare system. The difference is that conservatives see the government intervention in the healthcare industry as the main problem. (The Federal government pays 2/3 of all healthcare spending in the country, so our system is pretty “socialized” already.) Trump’s first step was an attempt to repeal Obamacare and start to return the healthcare system to more market-based solutions. However Congress was not willing to go through with it so we haven’t had any progress on healthcare since.
Conservative views are not simply a bunch of people arguing in bad faith.
