Outspoken Kiss star Gene Simmons has urged immigrants to the U.S. to learn English to succeed in life. The rocker, who himself is an immigrant, took aim at foreigners who refuse to perfect their English when they arrive in the U.S. in a recent interview with the Huffington Post. Simmons says, "I'm actually saying the thing that needs to be said because the politically-correct climate is bulls**t. You don't want to upset anybody by saying, 'Learn to speak goddamn English'. "So, as an immigrant, I'm telling you, 'Learn to speak goddamn English.' It is the key that will unlock the keys to the kingdom."
