Another way at looking at comparing today's political proponents to Nazis

Imagine Hitler said: "It's wrong to attack people based on religion, but only if their religion is christianity, islam, hinduism, sikhism, buddhism"

Random onlooker: "So basically, we can only attack Jews, but isn't that discrimation?"

Hitler: "No, because they have a disproportionate representations in positions of power, they got those positions unfairly because of who they are, and they oppress the rest of us victims"

Now, take your fringe leftist:

Fringe Leftist: "It's wrong to attack people based on religion, but only if their religion is judaism, islam, hinduism, sikhism, buddhism"
