How does this argument work for other deductions that also allow you to "fund personal causes"? For instance, the IRS allows you to deduct interest paid on student loans. I can get student loans to study anything I want, and doing so is arguably used to to advance my "personal agenda" (eg. getting a phd in economics so I can work in a thinktank). Should I be worried that the action was a "reflection of their personal politics" and therefore not get a tax break for it?
Feel free to repeat this argument for other deductions that the IRS offers: https://www.irs.gov/credits-deductions-for-individuals
