People cheer and conspiracy theorists on every side go wild. More neo-Nazis/KKK types go to prison.
there will be a hunt on the internet for these groups and this could lead to the death of the alt right
These types of white supremacists barely even used the Internet and thought Stormfront was run by Jews/was controlled opposition.
Prople start hating the alt-right almost a decade earlier
Also it would be interesting to see how it impacts politics
It is safe to assume that it would cause backlash against politicians who are considered too right-wing like Steve King
Also nationalist regimes would be seen with more suspicion and less admiration
How can anyone hate a movement which wouldn't exist for another decade? It's like saying the sinking of the Lusitania caused more people to hate the Nazis.
Right-wing Trutherism kicks in: the concert bombing was a plot by Democrats to distract attention away from Muslim terrorism. Additionally, fellow-travellers of the racist-right comb through rap lyrics to find evidence that whites are being provoked by black militants into this kind of action("Not that we support violent reprisals, of course, but we're not the ones who started this war."). About half of Republicans believe the first theory, the other half believe the second, and a not-insiginifcant number manage the cognitive feat of believing both.
Half of Republicans, seriously? You can't even get numbers that high for 9/11 truthers, and I'm pretty sure that Oklahoma City bomber conspiracies poll even lower as to number of believers. Hell, I wouldn't be surprised if the majority of conspiracies are instead about how the government did it to start a race war to kill all blacks and other black nationalist sort of conspiracies. Given the history of conspiracy theories in some black nationalist circles along similar lines (government created AIDS/crack cocaine to kill black people), this is probably going to be the case.
None of this dissaudes the FBI from investigating right-wing terror groups, though Republican leaders try to spin the bombers as lone-wolves, not connected with the wider conservative movement.
But they already had during the 90s, and most of those groups had the majority of their (small) membership imprisoned.
Thats one thing to do when its one guy shooting up a church and only killing half a dozen people but you absolutely cant spin the second largest terrorist in US history that was undeniebly done by a sizeable group. Its a hell of alot harder to spin a couple dozen co conspirators as lone wolfs or false flag operators then one or two and its borderline impossible to spin 300 dead. Did you miss the part about this bieng done by a right wing extremist GROUP.
Oklahoma City was almost entirely done by two people. You don't need a big group to commit a terrorist attack. Just look at the Aryan Republican Army, The Order, and other neo-Nazi terrorists in the US. Those weren't big groups.
