Any specific reason for wasp's to not like catholics??
majorty of far right supremacy groups in America like the KKK, neo Nazi's are protestant ..... its kind of like the sunni and shia, but the violence happened a long time ago in what was called the protestant reffermation and once the lines were drawn ie most of the norther European countries became majority protestant violence died down... but there was always a lingering feeling among some protestants and Catholics...
Its really the KKK that dose not like the Catholics for 2 reasons one as i said above the other because back when the KKK had maximum power in the 1910-1920 there was a lot of immigration of Irish and Italian.... who were Catholics.... the general fear among KKK members was the America was going to become a majority Catholic nation .... so the hatred towards Catholics.....
But that feeling has died down significantly since then and although the KKK dose not like Catholics it is willing to tolerate them and all their propaganda and hate is directed towards Blacks and other non white immigrants primarily....
The American far right is kind of a spectrum in a way... and they defiantly don't get along with each other for example:
KKK and neo Nazi's hate each other even though their ideology is almost the same except for a few minor differences, for one thing the KKK hate the Nazi's because most of the KKK's members had a father or grand father that fought the real Nazis in World War II.... Most neo Nazi groups want to merge with the KKK, as the KKK has more people and more of historical significance but the KKK is not going to let this happen...
There is another group called the Aryan Brotherhood, it is a prison organization that on the surface seems to be a neo Nazi style organization with only white members but the reality is that it allows members of mixed race into the organization and even Jews..... its more of a criminal organization rather than a racist group
Then there is the group called the Aryan Nations that is a coalition of all racist groups mixed with Christian religion.... they believe that god created the different races and meant for them to be separate and want to create separate nation for "white" christian people.... and this is the group that is really responsible for the majority of violence in the past 20 or so years.... It is not a clearly defined group as many members have different commitments to the group but the I think that its ideology is most consistent with what most of the racists in America believe ....
Aryan Nation is not a powerful group as they don't really have a lot of members but its the ideology that is the most important and it is specifically anti government, While traditional racist groups like the KKK never liked the federal government they never committed violent acts against it... I think that who ever is responsible for this attack had to have some influence form the Aryan brotherhood ideology
There are a whole other spectrum of groups that are not racists but are more anti federal government for a variety of reasons like gun control etc... its more likley that the person/group resonpible for this attack is a mix of this type with the Aryan brother hood
