I really think it is as simple as turning off all forms of government aid, public school for kids included, without proof of citizenship or green card for parents. Not a penny for free, not a morsel of bread on taxpayer dime, nothing, and a large number will self-deport.
Others will turn to crime, but that makes it easier to find and deport them.
The funny thing is I know some good people who teach in California but have drank the kool-aid and think our certification programs are top of the line. I think the main reason some of these teachers oppose others leaving state is they fear for their pension.
"But what does Ivan the Terrible have to do with the Earth today?"
"Is this a serious interview or not? I'll get to that eventually, but first let me continue to when Katherine the Great ceded the moon to the Poles."
I firmly believe that Japanese is very easy to learn to speak and understand compared to many languages, yet it is also likely the most difficult language to learn to read and write well.
The grammar is easy for any brain, western or otherwise, to wrap their head around so long as they are good at pattern recognition; compared to something like English, Japanese is incredibly consistent. Anyone who did well at math in school should be able to easily comprehend Japanese grammar. Yeah, they have a couple more conjugations for verbs based on respect/politeness, but the rules have few exceptions, so it isn't too difficult.
Vocabulary, while lacking Greek and Latin roots that simplify transferring word knowledge from one western language to another, is also very limited for non-academic Japanese. There simply aren't many synonyms in conversational (and anime) Japanese, context is typically in how the limited set of vocabulary is spoken. For instance, there really is only one word used for "big," "ooki." How many synonyms for big are there in common, everyday English? Likely over a dozen.
The written side is a bear, and I just have come to accept that, unless I move to Japan, I will never be motivated to learn to read and write Kanji past a basic level. Even in very common usage there just are too many characters, and it is often a 50/50 guess at pronunciation of Kanji.
Summary: learning any language is difficult, but for speaking and understanding Japanese, I believe it is one of the easier ones. Isolation has kept their grammar and vocabulary more fundamentally sound and simple compared to most other languages. Unfortunately, the reading and writing is incredibly difficult.
A lot of Indians are muslim, not the majority but a lot.
Also, Chinese can be really cool, but if they came from a well off family from mainland China, they likely have a LOT of the CCP propoganda baked into their brain, so it takes time and work for them to see the light, and some never do. Moreover, even if they break the brainwashing, they usually are careful because they know they are being monitored.
They don't realize how perfectly that sums up their movement: the people for trans rights are the demented criminals who are trying to kill off those who keep society safe and sane. Plus, there's the added layer of trannies literally being the real suicide squad.
Not even needed, I have at least one friends who is near fluent in Japanese that, if given the opportunity, would probably quit his current job to be an accurate translator/localized, especially since it really is a work from home position nowadays.
To your last point, I just know that quite a few little boys like Sonic the Hedgehog, like my cousin's sons. I saw with horror as one was on Youtube the Sonic furry fanart stuff that gets pushed on him in the recommendations.
I'm sure he watched some of it to start the cascade of recommendations, but the first video was almost certainly a YouTube recommendation only because he watched normal Sonic content, not degenerate furry crap.
And the degenerates will still play it, especially if everyone else likes it.
