It's hammered into people's lives too; there's no escaping it. Sooner or later, with either a little hammering or a lot, everyone will conform.

It sort of reminds me of how smoking was basically eliminated from any sort of establishment here in Canada. First it started with airplanes, then restaurants, then hotels, then bars, then basically there isn't anywhere to smoke except the street corners only if there isn't a person within 1 km. It took the last 20 years but, slowly but surely, it was forced upon everyone for this change. And now, the next generation wouldn't even know that, at one time, every coffee shop across the country once had a smoking section in it with a glass wall. Political correct speech, to me, is changing in a similar way. It starts with the small things until before you know it, all of it has changed and most don't even know it happened.
