I'm just going to leave this link as to why everything about this is wrong:
http://rationalwiki.org/wiki/Anti-racist_is_a_code_word_for_anti-white
Or if you don't feel like using the link, I will just summarize the basic inaccuracies:
1. This assumes that Asia and Africa are one monolithic entity where everyone and their cultures are the same. In reality they are very distinct from each other. For example the Arab- and Berber-dominated north Africa (hey a relatively diverse place!) is radically different culturally and demographically from the Congo or Mozambique.
2. Asian countries (mostly Japan) have been pressured to be more diverse, albeit to address issues with declining birthrates.
3. The semantics are odd. Why refer to the continents of Asia and Africa, but then switch to "White nations"? Why not say North America and/or Europe? Are you implying that there are areas in both continents that are not white? What defines a "white nation"? The latter is especially important. If they mean it as a "nation with a large white population" it doesn't work since racists like to consider South Africa one, even though at its peak the white population only accounted for 1/4 of the entire population. Likewise if they mean "nation that is strongly influenced by European traditions" it also doesn't work because Turkey, Russia, and Japan are never considered white by them.
4. Genocide is defined as "the deliberate killing of a large group of people, especially those of a particular ethnic group or nation". Needless to say, having black people moving in next to your house or having a Muslim date your daughter is NOT anywhere close to this.
5. You think that your tacky hastag will catch on/is clever. #NotAllHastagsAreEqual
I'll update this comment if I can think of anymore points.
