Judaism is a religion duh.
I think the point your trying to make is, if Jews are not a race then why Zionists claim this to be or why even Jews do this?
Well for one, Jews are known for their corrupt beliefs. All the bad characteristics in this world you can find in a Jew. They are cowards yet arrogant and hypocrites. That is why Allah has cursed them till the the day of Judgement! Just look at history, they were kicked out of every single place they wanted to settle into. Why? Because of their "I am God's chosen one" mentality. Anyways, Zionists on the other hand, are extreme version. They use Judaism as a shield but and proclaim it's a race (by recalling all "suffering" they've been through)... in actuality it's not suffering, it's humiliation, a punishment from Allah.
Talk about stereotyping. If they are cowards how come they were able to defeat the six nations that went to war with them. Jews are the most advanced people in this planet. Take any great company and you would find a jew in a very good position.
