I am not sure where you are getting the idea that people of Indian origin are asking for or getting any special consideration compared to Turkish or a Portuguese or any other ethnic groups.
A french guy raised in struggle will have as interesting a perspective as a brown guy raised the same way. They are both interesting and diverse hires regardless of their color.
See my point ? Diversity should be circumstance based and Im afraid sometimes, it's just sun-strength-on-the-skin-based. Maybe Im wrong there too ?
