No, it’s not “banned” but effectively it is. It’s illegal to proselytize. I mean, the Dalai Lama fled to India in the 50’s because of China. I won’t even get into Xinjiang’s labor camps. And no, race mixing is not a bad thing, but that is not what this is, especially when it’s done deliberately and forcefully. I like how you try to conflate race mixing with ethnic dilution. China aims to erase the Tibetan culture, not mix with it. There are way fewer Tibetans than Han. Magnitudes fewer. So fuck off with your weird sex shit and get off your high horse.
