Let me tell you a story: when Irish immigrants first came to the United States, they were decried as "white niggers;" viewed as sub-human, even African-Americans bitched about their savagery. People whined about their backwards customs, reluctance to adopt American customs, and higher birthrate. A lot of honkies were convinced they were a threat to genteel American society.

Now, no one gives a shit about Irish Americans. Irish men marry white women all the time without a fuss being kicked up. One day, your grandchildren will fail to have nightmares about towel-headed savages and castration. So shut up.
