If I made public my membership in a political organization with violent tendencies, I would expect a backlash, too.
Want to live successfully in the USA? Renounce any totalitarian political affiliations.
One of the tenets of becoming an American Citizen is to assimilate into OUR society, to learn our language and our history, to obey the laws, and strive to succeed within the strictures of our laws.
Failing to do that, more and more, you will find backlash which can lead to violence. IMO.
