I wonder how many terrorist (and “terrorist”) plots that were foiled were from compromised telegram messages. How many Ukrainian airstrikes were called from similar sources. My gut says a whole lot more than people think. Since nothing is encrypted, one backdoor is all the NSA needs to read everyone’s group messages. Like the much lamer version of Crypto AG, because in this case it’s an open secret.
You gloss over the part where even with the best intentions imaginable European immigration would have killed 90 % of American Natives with their new pathogens. No matter which way you slice it that is a scenario where European culture becomes the dominant culture, though it would certainly be nice not to have overt genocide and oppression sprinkled on top.
(Of course that’s not the case right now and the great replacement theory is a fascist invention, if that needs saying)
Also be careful not to infantilise immigrants. There is a marginal but highly visible issue happening for example where Saudi Arabia is funding Wahhabit (i.e. highly orthodox) mosques and imams in Europe that when combined with depressed socioeconomic opportunities fuels religious antagonism/radicalism particularly amongst particularly vulnerable teenage second generation immigrants. Is it an existential threat to European hegemony or something Europe is incapable of absorbing? Certainly not. Doesn’t mean it’s an issue we have to refuse to acknowledge in the name of our own leftist orthodoxy.
