A lot of conservative politics are predicated on ideas which, though objectively true, the left has sunk a lot of effort into making the direct communication of taboo. Hence, Republicans often have to walk around them, which can be awkward at times. Below I will break this taboo and name what these ideas are:
1. All racial groups in the United States have a positive in-group bias and a negative out-group bias, not just whites. In principle, anti-white racism is just as bad as anti-minority racism. In substance, anti-white racism is just as much a current threat to the rights of white Americans as anti-minority racism is to the rights of non-white Americans, even if the opposite was true 50+ years ago. In terms of cross-racial violent crimes, whites commit a disproportionately small number relative to their share of the population, and it plausibly might be the case that an outright majority are committed by non-white perpetrators against white victims. The occasional terror attack by a white supremacist against non-whites does not change this. For every one of these, there's a hundred or even a thousand single-victim incidents that don't make national headlines but are just as reprehensible.
2. Efforts to challenge anti-minority racism by whites are almost always undertaken in bad faith, because the anti-white biases of minority groups are not equally challenged, which makes said efforts merely a rhetorical bludgeon against whites. This is also counterproductive because it actively takes scrutiny off minority groups when it comes to their own problematic attitudes, making it less likely that they will change in the future, and it unduly fuels their sense of grievance toward whites, which can and often does translate to increased hostility and transgression.
3. A few of the demands of BLM were reasonable, such as body cams for police and being more proactive in trying officers who kill civilians under circumstances which might plausibly be murder. But the other demands were unreasonable, such as laxening our criminal code and incarcerating fewer people. It is incumbent on criminals not to break the law, and they are not entitled to have the consequences of their own crimes mitigated. If a disproportionately large number of black Americans suffer a worsened quality of life because they committed crimes, that's their problem. If disproportionately few privileged upper class whites are prosecuted for, say, recreational drug use, then the law ought to be enforced more consistently but the mere fact of said disparity does not entitled convicted criminals to get off the hook. The US may or may not laxen its drug laws in the future, whether for better or for worse, but those who knowingly break these laws while they're in effect deserve imprisonment and whatever the enduring consequences afterward. This is especially true for those who not only use but also deal drugs.
4. Too much democracy is a bad thing, because this always translates to a great many poor redistributing (i.e. stealing through "legal" means) from the rich, violating their property rights, or borrowing in the public name, which raises the national debt. It's morally justified to lessen the degree of democracy if there's nothing else that can be done to prevent this outcome, though oligarchy is also bad. Additionally, there's a de facto correlation between poverty and being part of a minority group. The more immigrants from poor countries who enter the US, the more the power of that voting bloc which would violate the property rights of the rich or raise the national debt.
5. That Asian and Jewish Americans are a "model" minority is not a racist or problematic idea. It's what every minority group in the US should've aspired to, but which many have fallen short of being. Had black Americans behaved like their Asian counterparts the last 50 years, the black-white income gap would've shrunk to less than 10% nationwide, assuming blacks didn't eventually surpass whites. Whatever the private prejudices of the capitalist class, they will in the aggregate do business with whomever it shows itself to be profitable. The reason why black Americans haven't escaped poverty is because their ancestors fell into costly behavior traps, which became intergenerational cycles. They chafe at the idea of the model minority because a large class of upper class Chinese-Americans, whose ancestors were once hated and discriminated against by whites, is a constant reminder to them that they've failed to improve their own lot.
6. If black Americans and so on wish to escape poverty, the only way out is to either escape said behavioral traps or adequately compensate for them through some virtue, like a strong entrepreneurial spirit. They vote Democrat in hopes of unmerited, harmful to others, and ultimately counterproductive to themselves shortcuts, and they resent Republicans for blocking this agenda.
7. None of the above is "bigotry". It is the plain truth, albeit a truth which most people have been cowed into silence when it comes to. Minority groups certainly will not take to heart criticisms that nobody save for avowed white supremacists are willing to tell them in the first place; since reconciliation is a two-way street that requires both parties to acknowledge what they're doing wrong, the existence of said taboo makes reconciliation impossible and will continue to perpetuate racial conflict going forward.
