Taking the actions of a few and calling it a baisc characteristic or a caste , cummunity or creed or taking action(using force, killing) against the cimmunity seems to be a trend. When Mahatma Gandhi was assassinated Brahmins faced it and probably are still facing it to some degree, after the assassination of Indira Gandhi, Sikhs faced it. Creating an issue and telling people who is to blame for it or who you should be scared of is the basic principal of the political game in vote bank politics.
