It doesn't work.
No one is going to perceive racist intent in a white guy asking another white guy to come and work the fields.
Firstly because there was none.
Replace Maher with Dave Chapelle and the response would be 100% justified, because it would be massively inappropriate to say that to a black guy. But it wasn't said to a black guy. At best it would have been horrendously tone deaf and people would have no problem with Chapelle or whoever pointing that out in a confrontational way.
I'd still find the response inappropriate though less so if Maher had used different language.
The slaves weren't invited to work the fields.
While we're talking about reality here, remember that
the argument in the past that field work was done via choice and want. This totally overlaps with the current neoliberal OS our culture has, where everyone has true freedom and isolationism that the sheer assertion that there's ideas of coercion via sufferange and power plays are argued as shams. Remember, our secular deity is the free market, and it always works morally and justly. No one is shackled or oppressed, apparently.
Saying terrorism is exclusively a Muslim thing is wholly untrue. If that isn't islamophobia I'm not sure what is.
If he said it was just only in the domain of Muslim actions, he's dead wrong. We have Christian shooters in this country this decade alone, but of course, as a Christian nation, there's always the scapegoating to the usual issues of isolationism, which again, loops with that neoliberal bit. Most Muslim countries don't have neoliberalism nor Christianity as their main systems, and thus are seen as a "all together" type of clumping. It's the usual hypocrisies of praising and blaming perceived ingroups and outgroups. Look at just the topic of race and how quick the white majority looks at whites as isolated beings, but blacks as clumps and units. It's the
same game. It's also done to subtly talk about people who "play" the game correctly or incorrectly, though this is another arena to normalize inequality and persecution, but I am likely pivoting away from the central point here.
I do believe Bill's points focus on the lack of reformist pushes that have led to a lot of blind acceptance of very toxic, very violent ideas, and this is hard to refute. What's particularly bad when it comes to attacking a belief, be it a religious or a worshipped belief, is that criticism is seen as combat. You criticize Islamic beliefs and you apparently hate all Muslims, which is as if criticizing Capitalism means you're a damn dirty commie. Our culture makes these quick jumps nearly any time examples like this arise, and of late, they arise weekly.
There's also the unfortunate factor that many today driven to violence via religious belief that hits the news are Muslims, which can help create the idea it's
only Muslims. After all, what happened with that Christian who shot up an abortion clinic, or more recently the self-proclaimed "Patriot" who killed two people defending Muslims on a train? They're coincidentally seen as standalone isolated events and not a damning view on a body of thought. Funny how that works in a white, Christian nation that likes to see itself as disconnected enough that you can't get the same levels of groupthink they proclaim radical Islam to have.
