Most republicans don't believe in defense or anything like that, they believe in returning money to their investors...I mean campaign contributors who are defense contractors. A contractor makes money selling contracts, whether they affect the actual defense capabilities of the country or not.
Also, Republicans (of whom I’m not one) believe that spending should be controlled by the states. It’s not that they don’t believe in defense - they realize it’s more effective to invest in drones and use nuclear deterrence. Those are more effective and cheaper in terms of lives as well as money. This aligns with the US’s new isolationist strategy as it withdraws from the world.
Tell me which parts of “Diversity, Equity, Inclusion” you disagree with, then tell me how those things tie to Marxism?
Like, if a project studying biodiversity is cut, is that because it is "related to DEI initiatives" because it shared the word "diversity"?
How many of the laid-off VA staff were DEI? The laid-off forest rangers?
How much of USAID was DEI? The Trump administration says the cut was due to wasteful spending and fraud, not DEI.
How do the cuts in DEI initiatives compare to the massive cuts to indirect grant monies?
If the Republicans believe spending should be more controlled by the states, they have a majority and can, you know, change the law. We have a representative democracy to help balance national interests, rather than the interests of a king.
I don't think we can regard threats to annex Greenland, Canada, or the Panama Canal as part of an isolationist policy. Such threats are more closely aligned with expansionism. An isolationist government would not be involved in international negotiations involving Ukraine, or providing support to Israel, to start.
FWIW, DEI is no more steeped in Marxist philosophy than the Freedman's Bureau, public libraries, or the FDIC. As far as I can tell, "Marxism" when used this way is a boogieman term used to scare off any critique of capitalism or its effects, little different than how Republicans sneered that Dukakis was an "L word", castigating the word "liberal." Both terms are used as rhetorical propaganda.
Given the influence Marx had on studying "class relations, social conflict, and social transformation" (https://en.wikipedia.org/wiki/Marxism), it's all too easy to say that any study of those topics must be Marxism, and therefore fomenting a communist revolution.
I've looked through it a few times to answer the same curiosity you have (I want more specifics, not just the stuff that fits in a tweet). But it still leaves me with questions because I don't know how much of these claims is actually accurate.
First, if you look up progressive academic theorists [1] you will see that they are largely inspired by Marxist philosophy either directly or indirectly. The right are diametrically opposed to Marxism because it relies on an assumption that Man can rise above his Animal instincts. But, man can't, even with best intentions (i.e. ethics professors do not behave more ethically than non-ethicists) [2][3].
There is a belief by the right that the great majority of people working in government and government related industries (e.g. NGOs) have come out of liberal arts programs that were inspired by the academics listed. They also believe that progressive ideology has steeped into the sciences.
I believe the right's goal is total dismantling of the executive branch. The point is really to destroy any power that the executive has down to the bare minimum so that the risk of a king is eliminated. It's interesting that they put a group of potential tyrants in charge of all of this - it's almost as if they want to show everyone how bad of an idea it is for the president to have so much control.
They generally believe that differing cultures are a good thing but because of Human nature integration cannot work. Therefore, in a state system, they believe one should be allowed to move to the state of their choice and enjoy whatever culture they want given the constraints of the constitution.
Furthermore, they believe the constitution is the only way for lasting peace. It sets the bare minimum for a social contract that works across cultures and people. It gives a framework where people can be culturally different but equal. And, they hope to expand the US to other countries voluntarily (we hope) so that those countries may also share in its glory.
