Well.
Not really, actually.
You can't apply the aggregate to the individual. For the same reason that you can't say 'X populations are less skilled at Z on average, therefore Y individual who is a member of X population will be less skilled at Z' accurately (someone with a disease that has a 40% rate of survival is not 60% dead), you can't show that any one person is replacing anyone, particularly not in any malicious way.
Demographic replacement is a very odd issue, morally speaking. Opposition to it is both strange and nonsensical as well as eminently practical. Though I suspect once the Republican party stops being the party of white people (in about 16-20 years), mostly because they can't afford to be anymore, that the practicality of it will be much reduced. As it is now, if you're Republican, demographic shift also means that people are more likely to be voted in who would have things that would oppose your values, since most minorities vote Democrat. Doesn't even matter whether you're racist or not, from a practical standpoint, the Democrats are trying to accelerate a change in demographics that would empower them and make you less likely to get things you want. You can be a minority and still think this way. Hell, from what I can tell a rather large proportion of minority populations are socially conservative. Asians, Hispanics, Muslims, African-Americans...religious upbringing tends to (not always, just tendencies) make one conservative.
Sidenote: Covenant, as much as the social justice movement exacerbates the problem ('cultural appropriation'. Either it means stereotyping, which we already have a word for, or it means 'what does this minority culture group tend to do? okay, dominant culture group, you're not allowed to do that', which is just segregation/anti-assimilation by another name I mean fucking hell), identity politics is not preferred by the left. It's become a large part of it's strategy, yes, by necessity, because from what I can tell, identity politics was started by the right, with WASPs, and moved to broader groups that don't all line up quite perfectly from there. Minority groups use that sort of thing as a defense mechanism, not an assault tactic.
No idea who's up next on the Dem ticket tho
And I will say I did not think Trump would win, or really could win, because polls and temperament. But hopefully we're seeing that when he's not campaigning he has a somewhat less caustic approach. Fucking hell, it's still so weird that he'll go down in history books now for the rest of United States' existence.
