Your argument is scientifically false.It is lazy and unintellectual.
No Racism, Zionism etc. are all different. Racism IS based on biological, intellectual and cultural superiority. Zionism on the other hand, is Jewish Nationalism based on Jewish identity. Both are bad and result in discrimination. But being "bad" and being "discriminatory" is where their similarities end.
There is no biological races, there is no biological basis for racism.
All discrimination is cultural or intellectual and its all based on supremacy.
All forms of nationalism are based on racial/cultural supremacy of one people over another.
Be it Hindu, Jewish, or White supremacy. Its all the same.
