I do not believe that vast majority Americans are so hateful towards people such as myself that the only thing keeping them from discriminating against me is the law commanding their virtue.
First, you make it sound like they have to be super hateful. All discrimination takes is a preference.
Second, it doesn't take a majority to hurt you. Imagine there are 3 companies in your area currently hiring for a position like yours, and there are 2 white men that are searching for the same job. If just 1 will absolutely not hire you because of your race or religion. Because you're competing from one of only two open positions available to you, and the white men have three options available to them, they have more room for error. They can command higher salaries, and you might have to be willing to take a pay cut just to make sure you get one of the two that will hire you.
Now, fast forward three years, and you're looking around for another position. Maybe there are four companies hiring this time, and none of them will discriminate, but they ask how much you made at your last job as part of the interview process. Now suddenly you stating your previous salary as lower than some other white candidates makes you look like you're less qualified.
I am not so sure that is the case that such a blanket statement could be made. Perhaps you are right about some of the more anarcho-capitalist conservatives who believe that the free market is the solution to every conceivable social problem. But I find that most conservatives I find are perfectly happy with publicly-funded or subsidized services, but they prefer them funded by the taxpayers who immediately stand to benefit and under local government control rather than the control of distant and less-accountable State governments or the Federal government.
No, that's just their bull**** excuse to get the federal government out of the way so that they can then say **** it, and not have a public hospital at all. Or potentially even worse. Part of the reason why we have a federal government is that our founding fathers were concerned about "factions." Meaning they knew it would be much easier for a group of single-minded radicals to obtain control over an individual state than it would be for them to get control of the whole country. Think about Mormons in Utah or the Quakers in early Pennsylvania.
The KKK, Neo-Nazis, and general white supremacists aren't a massive group of people, but if they all decided to move to the same state(or as is currently the case, the Republican party) they would be capable of controlling it and implementing their horribly racist policies there driving anybody they don't like out. They could ensure that the public hospitals in their city or state would not save Atheists and Arabs even if individual doctors wanted to. Or an even more likely scenario, they would take over control of local public schools and teach alternate versions of history, biology, and earth science to brainwash children into their hateful ideology making it impossible for you to send your children there.
This is already a problem in many parts of the south. White Supremacists have a ton of power within the Republican party in states like Alabama and Mississippi. The majority of the state might not support white supremacy, but 51% still vote Republican every time because of guns, god, and tax cuts. This gives white supremacy huge influence in these local governments which is why the federal government is necessary to protect your right.
Unfortunately now this has spread to the federal government as well. I don't want to alarm you, but I encourage you to realize how close the current administration may be to war with Iran. If something like that happens don't think for one second that your fellow conservatives won't be open to the idea of internment camps for Iranian Americans(or frankly any Arab American) just like they had for the Japanese during WWII. I assure you, it's not as far-fetched as some might think.
When I say "public agencies" or "public businesses" I do not mean simply serving members of the public (which is technically anyone and everyone). I am referring to a business directly subsidized or funded by public monies, i.e., taxes collected by the government, rather than through private voluntary exchanges for goods and services.
Yes, I understand that, but whether you have private voluntary customers or not, the roads that those customers use to get to that business and the infrastructure they use to ship their goods, and the police that drove past their storefront every night to ward off criminals are all paid for using tax dollars.
