The canary has been screaming its lungs out since Bill Clinton introduced his racist anti-immigrant bill in 1997, but both Republicans and Democrats have not only ignored its cries, but hastened its situation. Both parties have created this. Don’t think this won’t affect us all.
Biden bragged about deporting even more than Trump, and do you think he closed the concentration camps? Harris ran on an anti-immigrant platform and even ran a wildly racist campaign ad. Obama was notorious for imprisoning and deporting Latinx immigrants. And Bill Clinton is solely responsible for spreading the concept of an “illegal immigrant” with his 1997 IIRIRA. Yes, Clinton is the one who did the kickoff for the anti-immigration trend we’ve been suffering under ever since.
Maybe you’re young, maybe you don’t have family who are personally impacted, maybe you haven’t read history, but trust me when I say the Democrats are a racist party that fully subscribe to and act on using Eugenicist rhetoric as their platform. They are just as complicit as Republicans. (They just try to sound more polite so they don’t offend white liberals.)
So to answer your question: Yes, it happened under Biden. The difference is liberals failed to speak against it (and in many cases even excused it) because the villain was wearing a blue tie.
