If Trump and the republican congress's healthcare policy were put into effect, millions of people would lose their health insurance. I know how shitty it can be to go about health insurance with a chronic illness. I expect thousands of people to die if this policy were put into place.
What the fuck does it mean to disagree with me about policy but agree with me in principle, in this case? Am I supposed to ignore the fact that political decisions impact the material lives of actual human beings? Am I supposed to play polite with politics that will harm people I care about because it's more important to agree in principle than to agree on actual concrete policy?
People who complain about how close-minded it is to be vehemently against Trump and by corollary people who put Trump into power never mention actual policies and how those policy differences actually impact people. It is always vague statements about politics in the abstract.
Politics in the abstract is never the reason for anything.
