Exactly right. But they’ll err on the side of PC and assert that though it doesn’t qualify under the legal definition of “discrimination” it does anyway, because it must. So they choose “sex” because, um, gay people have sex with eachother? No, no, because they’re being discriminated against for not being women. Or not being men, if the wife is the one in the military.
Whatever else happens, death, taxes, and “sexual orientation” being officially added to the list will. No again, it must be more than that. Not merely orientation, but we must not discriminate against those who are “differently married.”
Eventually we won’t be able to discriminate at all. And what’s the opposite of discrimination. Fairness? Absolutely not. Tolerance? That’s what they’d have you think. I hate inappropriately sciency words, but the answer is: dysgeusia, or lack of taste.
The opposite of discrimination would be indiscriminate and undiscerning, both very apt descriptions of the modern liberal.
