Additionally, a subset of these people also believe that it should be socially acceptable to say disparaging things about blacks, Jews, and other groups that "enjoy" social protection from such behavior.

Drug addiction absolutely is a political issue, and a hot one at that. Same with race issues and immigration. White bread or wheat would be an example of a non-political issue.
It's possible that you live in a country where these are not political issues, but I'm from the USA and these topics are discussed by politicians on a daily basis. They have the secret to fixing the heroin issue, or the immigration crisis, or the Muslim terrorists, etc.
I believe the recent presidential election has proven otherwise.
