What’s the best way to unpack this?

I don't know how much our members know about MMT - I'm certainly no expert on it. However, I don't see fallacies here - it would be a case of asking for evidence for those points (1-5), and then either accepting or refuting that evidence.

I don't see any fallacies at all here, just a series of statements and claims, unsupported by evidence.

My guess is that you [James] posted this on the wrong site. Perhaps an MMT forum would give better results.

Just a bunch of assertions, but not really any logical fallacies. Wrong forum, I guess. 

Hey Everyone,

Apologies, let me be a bit clearer I'm not looking to examine the logic behind the bulleted MMT list, I'm in the process of educating myself on it enough to further that part of the discussion with the guy that posted it. 

I'm more concerned with responding to 

let me guess, you are a fan of MMT? Wouldn't surprise me. It is trash for many reasons, here are five. Regarding the debt ceiling, this is a constant game and always has been. It is more swamp theatre and to believe otherwise is foolish. While the spending bill is also theatre, it sets us further down the path of insolvency. We must raise the debt ceiling because there is no choice, but there is a choice not to apply $22,000+ to the debt of every single American taxpayer under one pork bill. The only reason why we can print our own money is because the world uses the dollar. Once we are replaced and no longer the "bread basket currency of the world" our problems skyrocket and spending our way out won't be an option.

It seems to me that "let me guess, you are a fan of MMT? Wouldn't surprise me," is an ad hominem as it is directed towards me in an attempt to impugn my character and position. 

I also feel that "Once we are replaced and no longer the "bread basket currency of the world" our problems skyrocket and spending our way out won't be an option," is a slippery slope.

The whole statement comes off more as an appeal to emotion full of FUD. 

Thanks for any additional feedback. 

"let me guess, you are a fan of MMT? Wouldn't surprise me,"

It's an off-handed comment. Doesn't exactly qualify as ad hominem since it isn't an open attempt to discredit you.

If they suggested you're not worth paying attention to  because  you support MMT, then this could qualify as ad hominem.

"Once we are replaced and no longer the "bread basket currency of the world" our problems skyrocket and spending our way out won't be an option,"

More like an unsupported statement (that 'we' will be replaced, and our currency will no longer be 'the world's bread basket').
