Actually they do want to, and are getting it courtesy of a law pushed through by the left in the late nineties. What I was referring to is that the CDU and CSU - political parties you apparently like, vehemently opposed the change. Just a few months ago a leading CDU politician based his campaign against 'immigrant violence', making no distinction between immigrants and those born and raised in Germany. Also over the past decade CSU politicians have argued that 'immigrants' born and raised in Germany should be deported to their 'home country' if they commit crimes.
