"Liberals often demand we reduce/ eliminate subsidies for fossil fuels. I haven't heard of a liberal willing to compromise there. Example if a republican proposed a bill that would commit the US to reducing carbon emissions by 50% in 30 years; but protected coal subsidies would that bill pass? No."
First of all, this is a joke of an analogy, and you clearly don't actually understand how environmental protection works on an economic scale (something that many, many liberals are clueless about as well), because reducing subsidies for fossil fuels is paramount to reducing emissions. Other than major regulations, which nobody ever ends up happy with and never sticks beyond 8 years, the only way this happens is if the free market is able to dictate what sorts of energy production and what sort of energy standards are the best for consumers. That means that whatever part of the energy market is blended best with cheap products and service, reliability, accessibility, and whatever other qualities consumers want is going to be the part of the energy market that takes over. It has been shown time and time again that renewable energy sources like solar and wind can compete with fossil fuels, natural gas, coal, and other non-renewable, damaging energy sources and that the capabilities of batteries as far as storing energy goes could meet the standards of the largest buildings, the biggest warehouses, and whatever other challenge you want to throw their way. The reason that we haven't turned a corner in our energy standards and therefore cut our carbon emissions, or even committed to cutting our carbon emissions, is because the fossil fuel industry is heavily subsidized the point where it has an inherent economic advantage over its newer competitors. This will never change so long as corporate interests are walking all over our government officials, ruining the sort of connectivity with the local community that you see as so important by pushing the interests of corporate conglomerates over the interests of those communities like those in WV that would benefit hugely from reducing their financial dependence on a dying industry.
These issues are tied together in ways that so-called moderates in the USA (the rest of the world that isn't Russia calls you right-wing, by the way) do not understand. You seem to think that we can solve the problems that we have by compromising and by working together, which is so true! You forget, though, that the government is corrupted, and you forget that there are interests that are way, way above your - or my - head that are getting in the way of restoring a free market economy and allowing a socio-capitalist system to work as it is intended: free, elastic, though at times regulated with the best interests of the greatest number in mind, and widely beneficial, whether you're a low-wage worker, a CEO, or somewhere in between.
Look at the race that just took place in Georgia. The two candidates spent something like $60,000,000 on campaigning, advertisements, and whatever else - for a single spot in the House! There is absolutely no fucking way in hell that all of that money came from within that district. The mass of outside influences that worked to sway that election, from corporate interests that supported Handel to the Democratic Party for some reason thinking that a Jon Ossoff win was just the momentum they needed going into midterms in 1.5 years (why?????), made that race what it was, not the people in that community. I don't know if the people of the 6th District in Georgia wanted such a high-profile race, but it is pretty clear that in a race where Ossoff spent 6 times more than Handel, he stood a chance in a district heavily gerrymandered by Republicans to never go left again. That's what money does, and it's not coming from you and me; it's coming from people who have interests beyond the norm in mind.
There are plenty of liberals who don't acknowledge this as well, and they fuel the manipulated left-right dichotomy that you rightly believe plagues politics. If there were a large enough group of liberals and a group of conservatives that were willing to put corrupt politics aside and have discussions amongst one another, listening skeptically to the other side but listening all the same, then politics as you seem to envision could actually happen in the United States. Those people, though, in the system that exists now, would be shortly run out of power by the money that flows in every single election campaign by interests that meet behind closed doors and don't talk to constituents, or care about constituents, or even have a vested interest in the district vote they are pumping money into other than the specific person running for the seat. If you want to change that, you have to attack a different c-word: corruption. Compromise won't come until that is dealt with.
