They are buses to bring Guest workers from Palestinian cities into Israel proper. Theres no law saying non palestinians cant use them but the majority of people who will be using them will be palestinian based on their departure location and the fact few israelis want/can go to some random Palestinian village.
If anything Israel is doing them a good thing by providing these palestinians who would in any other case be unemployed not only with an opportunity for employment but with free public transportation.
The arguments and criticism that should be raised is not Israeli Apartheid which is ridiculous but rather the inefficiency of public transportation.
Also Yes Miss Israel 2013 is Ethiopian. If you dont know where Ethiopia is it is in East Africa. So yes she is African. If you dont know what African is it means shes black. People love to ignore that stuff and find any little story on Israel and bash it left and right.
