The way I see it discrimination has nothing to do with laws…it’s the result of perceived differences based on any aspect of life that highlights different vies on a given subject.
I can give as an example the new situation in South Africa where discrimination was constituted in the countries’ laws. 8 years after the scraping of all the apartheid laws in reality nothing has changed. Black people are still being treated badly in most places. What’s really interesting to see is a “reverse discrimination” situation where the black people, now in position of power, mistreat the whites. What’s even more interesting is to see how much discrimination is being practised among the blacks themselves. This is based on diverse cultures and tribalism.
More or less the same applies to the US…changing the discriminating laws did very little to eliminate discrimination.
In a nut shell, changing laws is not a solution. If after 3,4 generations of living together with the Arabs in Israel didn’t change anything, then I don’t think something will ever would.
