You know you don't have to always accept government overreach under the guise of "fairness." It's not fair, it was never fair, why are you expecting it to be fair?
Just look at how the US treats "ecoterrorists" versus white supremacist; or if you want historical examples look at how the FBI treated labor groups versus fascists ones in the 20s, 30s, 40s, 50s, 60s, and 70s (no need to worry about the decades after, they killed enough leaders to stop leftwing voices in the US).
Labor groups up to and including in the 60s were fiercely anti-immigration [1], and wanted to expand laws like the Chinese Exclusion act. You would call them white supremacist today. But as you say, the FBI did its job, and eventually the unions accepted immigration, just like capital wanted. Now Amazon can release a study showing diversity impedes unions [2], and Wikipedia helpfully summarizes it to give the opposite impression [3], while the FBI can better spend its time investigating "It's okay to be white" as terrorism [4], libeling whites with fabricated extremism cases [5], and taking instruction from the ADL [6].
