What traveling has done has made me appreciate homogenous societies and strong cultural traditions more- no matter the race- I've been to every continent and just about every region on the planet and loved pretty much every country I've been to for different reasons and the people within. The flip side of this though, where I may be called racist, is that this experience has even further strengthened my anti-immigrant stance in the West, and that we really need to do something to take our own countries back. However, this olive branch is extended to non-Western countries too- seeing other non-Western countries get flooded with immigrants not from their country or even over-tourism (eg Japan)- even from other Westerners- makes me just as sick as seeing Western Europe get flooded with immigrants who are clearly not from there. For example, watching Germany get flooded with Turkish immigrants is sad and frustrating to see, but I have been to Turkey before and loved Turkey and the Turkish people within Turkey, and in return I feel bad that Turkey itself is flooded with immigrants from Syria. I think we just need a few decades where we just put this globalist experiment on pause and see if this is the direction we still want to go in, the whole world is way too over socialized at the moment and its actually causing global relations to worsen- not improve.

The real problem with divisions of species isn't that they are just guidelines, but that nobody can agree on the rules. Evolutionary biologists have proposed almost 30 different species definitions (called "species concepts") over the years, and none of them apply to all organisms. For example, the "no fertile offspring" definition is a paraphrase of one of the most popular species concepts called the Biological Species Concept (BSC), which actually states that a species is "a population or group of populations reproductively isolated from other such groups". "Reproductively isolated" in this case can mean "no fertile offspring", but it can also mean "they never encounter each other" or "they don't see each other as potential mates". The problems with the BSC are: 1. it doesn't work for organisms that reproduce asexually, 2. lots of organisms we would otherwise call different species have hybrids from time to time, and 3. reproductive isolation is actually really difficult to test (many organisms will hybridize in captivity but almost never in nature). As I said, there's like 30 more definitions of species that have been proposed, and most of them are slight modifications of other species concepts to fix problems with them (and introducing new problems lol). Some researchers have tried to come up with a definition that unifies all these different definitions (e.g. "a species is an independently-evolving metapopulation lineage"), but unified definitions fall apart because they're almost impossible to apply in the real world (how do you determine if something is "independently-evolving" or part of a metapopulation?).
