Chicanos have the same issue, we have a lot of traitors working in the police force and ICE. These people don’t consider themselves “Mexican”, which is ironic since reactionaries definitely don’t consider them to be Anglos.
In Texas, these people will call themselves “Tejanos” but never Mexican. It’s crazy in that it’s an allegiance that’s completely one-sided. It’s also a negation of history considering that Texas used to be Mexican territory and before that, indigenous.
Edit: Tejanos serving in ICE and the police are our generation’s version of “Jews for Hitler”. It made no sense back then and it makes no sense now.
