Fact: You cannot be secure in Zionism but can be in other religions. As Zionism only supports Oppression or a system which supports Oppression, Injustice and brutality. I see many other religions like Orthodox Judaism, Christianity, Buddhism, Atheism, Shiite supports humanity while Zionism is just Oppression, Injustice and brutality. The people who follows Zionism claims that other religions are fair but it is not the fact. They are Hypocrites. As an Atheist, I know this very well. Atheism just supports humanity. It does not blame anyone or anything. It just supports justice.
I think the exact same holds true for Islam or even Christianity. The problem is not the religion itself but rather extremist who misuse the religion for their personal agenda. Humans have fought wards based on religion for thousands of years. But in the end it was just people who did bad things. Saying that a complete religion is evil is wrong, every religion has good and bad people.
Looking at your statement, he maybe even part of the extremist you're talking about, but we don't know his specific religion but he is clearly someone who has hatred towards those people who believed in Zionisim.
