That's why it's an insulting analogy. The Blacks on the plantation supported the master's livelihood and family under the use of inhumane force. Black people aren't the only ones who are dependent on government, Black people aren't forced to go on government assistance. Why do some people like to define the majority of hard working Black people by a minority of non working Black people who are on government assistance? Think about it.
I've been accused of "acting White" before by SOME Black people. It happened when I was a young kid. Guess what; it was done by a VERY small MINORITY of Black people that I interacted with. You don't see me defining "the Blacks" as a whole by the actions of a minority of them.
I know that they don't think that they "literally think that someone is on a plantation". They just use that as another way of calling Black people who vote democrat *******. It's the PC way of doing it and done by people who are a piece of shit.
