These all seem like really bad examples, panic over trans people has some very real, very British sources and 15 minute cities (and related concepts like LTNs and the ULEZ) is not something regularly discussed in the US.
Much better examples are US Southwest/Californian concerns around water scarcity being imported to places where water is not scarce, or similar concerns around emissions from electricity generation being imported to places that use high amounts of renewables/nuclear energy. Another example is civilian disarmament fear mongering switching from being about cheap handguns to "assault weapons" after DC v Heller.
The reaction to George Floyd in UK was quite strange, with "don't shoot" protests and "defund the police", when the UK police is not even armed and gets paid like half of their American counterparts.
