Fifty years ago, that “third” of the population might well have represented 90% or more. What you're describing is, at its core, isn’t always a tangible act you can point to; it’s often an unease, a gut feeling, or an instinctive reaction to what feels “other.” People say things that make you uncomfortable, and that discomfort becomes the lens through which you judge whether something is racist.
But here’s the thing: feelings, even when valid, don’t grant you the authority to dismiss or police the expressions of others. If someone’s words or actions make you uncomfortable, that discomfort is real—but it doesn’t automatically mean the other person is wrong or that their intent was malicious. Context matters, intent matters, and the burden of proof shouldn’t rest solely on the speaker to justify their words because someone feels uneasy.
