Never believe that anti-Semites neotankies are completely unaware of the absurdity of their replies. They know that their remarks are frivolous, open to challenge.
But they are amusing themselves, for it is their adversary who is obliged to use words responsibly, since he believes in words. The anti-Semites neotankies have the right to play. They even like to play with discourse for, by giving ridiculous reasons, they discredit the seriousness of their interlocutors.
They delight in acting in bad faith, since they seek not to persuade by sound argument but to intimidate and disconcert.
Already happening, m80. Those who are struggling to get into Western countries are generally not the ones with advanced degrees. Most Western countries are pretty open towards offering residency to those with specialized skills and education.
While the current system is nowhere near perfect, you can't just let everyone that wants to migrate actually do it. Whether you like it or not, there is a significant portion in every society that would vote for anyone that promises to close the border, as is evident by the rise of right-wing groups stirring up hatred against migrants all over western countries. You will achieve very little if you force the issue and incite a major backlash.
Poland and the baltic states are in Schengen. Bulgaria and Romania are about to join too. Turkey, Ukraine, Albania, North Macedonia and even Serbia might join in the future. The Serbia one will be hard, considering how many serbians are anti-West, but it is also a very crucial one because that would mean the entirety of the Danube river will be in EU.
The Danube river is navigable and it can take things from the Black Sea to Germany and anywhere in between. This should create a significant economic boost for all the countries involved, even neighbouring countries like Greece, since boats can dock in Greece and then drive a few kms to Bulgaria and Romania Danube river.
China, who is already owning the biggest port in Greece(and one of the biggest in Europe), is already preparing to invest on that second port that could link to Danube river. Then again with the new Cold War escalating, we might see the death of globalization. But still, having an alternative route for commerce is a pretty big deal.
Unironically, though, yeah, dramatically increase immigration. Immigrants are less likely to commit crimes, less likely to not work, far less likely to draw on social services, and more likely to start businesses. Plus, they can help correct demographic declines in a sustainable manner.
