Being invested at an identity level is a human trait, not a Republican or MAGA one. It’s not “lately”, it’s all of human history.

We all readily recognize the blind spots in people we consider part of an out-group. Becoming more aware of the blind spots of people we consider fellow in-group members, and especially in ourselves, is more difficult, but I believe important to strive for. Having blind spots is natural. Recognizing them and trying to compensate for them in our thinking can benefit decision-making.

In the case of “are the tattoos on this guy’s fingers MS13-related”, there is way more substantive discussion to be had than demanding the guy’s girlfriend dig up and share publicly a years-old couple’s picture without the emoji. Some quotes below if they are of interest, and the article has a picture with the full fingers and their tattoos fully visible in case that really was what you were going for. https://www.cnn.com/2025/05/01/politics/abrego-garcias-tattoos-explainer

“I see a bunch of symbols that could be interpreted any number of ways,” Jorja Leap, a University of California, Los Angeles professor who has served as an expert gang witness in court, told CNN.

…“These are definitely NOT MS-13 tattoos,” Thomas Ward, a University of Southern California professor who spent years embedded with MS-13 researching the gang, and is the author of an ethnography that studies MS-13, said in an email.

…While some gangs will opt for more low-profile or ambiguous means of identifying members to evade detection from law enforcement or rival gang members, MS-13 tattoos, according to Leap, aren’t exactly subtle. They are used to market the gang’s brutality.

“MS-13 members have tattoos that say ‘MS-13,’” Leap said. “They’re not head-scratchers; they’re billboards. There’s no ambiguity.”

Birthers claimed for years that seeing Obama’s long form birth certificate would alleviate their citizenship concerns. Spoiler: it didn’t, they moved the goal posts.

Once people are identity-level invested in something being true - in this case that deportations are about public safety and not racism, because no way could they or people they respect be racist - sinking time into producing evidence for them is futile. It is no longer about facts, it’s about identity. Sometimes people break out of these self-imposed mental prisons if a main trusted person who helped lead them there loses their trust for an unrelated reason (not one that had become identity-latched). Sometimes being welcomed into a different community that fulfills those identity needs will let them see their previously identity-latched falsehoods as false. But evidence is always futile.
