Zionists and their propagandists frequently try to point out that there are Arab members of the Knesset as 'proof' of a progressive, diverse, multicultural, egalitarian democracy where there is no apartheid or supremacy of any kind.
Interestingly, apologists for segregation and Jim Crow laws in the US resorted to similar tactics, pointing out that there were black members of Congress elected as early as 1887, and that Blacks 'had it good' and were equal too - just merely 'separate' in their equal-ness.
Obviously, I think most Americans today would scoff (and even laugh) at the notion that anything resembling equality existed in the US in 1887. The US remained an apartheid state up until the late 60's or early 70's when the last remnants of Jim Crow were finally struck down, and schools were finally integrated.
That's not to undermine the accomplishments of Joseph Rainey of South Carolina and Senator Hiram Revels of Mississippi who successfully ran for congress just 5 years after the abolition of slavery in the US. But, to suggest that it 'proved' that anything resembling true equality existed at that time in the US is laughable.
