There's plenty of pro-Zionist propaganda written and distributed in English in the USA, and my tax dollars go to fund the Israeli military, and I can read the reports my own country publishes in English just fine.

So, I will say whatever I want about Zionism since I am helping to fund it involuntarily simply by being a US citizen.

Also, I did not say one cannot speak about a topic if one does not speak a particular language. My point is that someone who speaks the language a primary source is written in will have an advantage in not relying on a translation to read it. There are plenty of sources documenting the ideology and sins of Zionism in English that I can understand just fine as a native English speaker.
