I always thought it strange when they say that (a) Israel is the homeland of all the Jews, but (b) Jews are not classified as Asians. Israel is not in Europe, it is not in Africa, it is in Asia. Armenians and Georgians are also Asians, as are a huge number of Russians. Asia is quite vast.
Of course, Asia and Europe are not actually separate continents as are all the other continents, separated by water and joined only by small land bridges, if at all.
The division between Asia and Europe is pretty much defined by man rather than geography.
