Sir, I think it's been established by a certain mod that any negative meme or comment about a leftist or one of their darlings must be 100% correct to include spelling and grammar. Learn it and live by it!
This is a somewhat nuanced issue, IMO.
McCain was a Republican that supported good policy even if it meant personal loss, like the law that Citizens United struck down. He was someone that both sides respected because he voted on principle and not down party lines (which is something that would be required of way more than 1 guy if a utopian individual liberty government is an actual ideal).
His Obamacare vote in August 2017 was 100% consistent with the above qualities. I’m not a fan of Obamacare, and I never have been, but this administration has shown time and time again that they don’t have the capacity to dictate clear expectations or policy guidelines to Congress. You saw it with the tax bill which was largely hammered out by Ryan and McConnel and you saw it with the wall and the emergency declarations where republicans reach a compromise and think they’ve satisfied Trump and he comes out and says no I’ve changed my mind. What they were planning to do was to remove a significant portion of regulatiory code regarding health insurance and they had no plan for how to fix it. It would have been a complete disaster for the Republican Party, they would have gotten absolutely destroyed in the 2018 midterms where they already got abused by the idea that they wanted to take away healthcare.
The reason he gets defended by the left, I assume, is because he was respected, and it’s sad to see people denigrate a respectable man in favor of somebody like Donald Trump. The fact that so many are so ready to choose Trump over McCain and to believe easily disprovable ******** like that meme is support for the liberal/never trump theory that Trump is having a negative impact on basic human decency and supports the idea that that harm will continue beyond his presidency.
Edit- this was in response to your post but not necessarily saying you’re in this boat. There are valid policy reasons to disagree with McCain, although the presumed validity of those reasons may be called into question by the fact that somebody is obviously resorting to pure fiction to try to make him into some sort of evil monster, rather than addressing his actual legacy.
