He's not saying that Allah and his army is fighting with Palestinians, He's not saying that magic birds will come holding rocks and start hitting the occupation forces, He is not saying that believing in Allah will destroy the Zionist entity, He is saying that the Muslim people fighting for Palestine right now with the Muslim doctrine and Islamic belief have Islam as a driving force for them, his post was not out of nowhere but an answer to some who DM'ed him and messaged him about Islam and he provided sources for anyone interested in learning about Islam, he didn't even ask anyone to convert, there's nothing idealistic in what he said. I am not educated about Joram van Klaveren so I will not comment on that.

A comrade on Hexbear posted this quote from the Central Committee of the CPC which i think is very appropriate:

"We Communists are atheists and must unremittingly propagate atheism. Yet at the same time we must understand that it will be fruitless and extremely harmful to use simple coercion in dealing with the people’s ideological and spiritual questions–and this includes religious questions. We must further understand that at the present historical stage the difference that exists between the mass of believers and nonbelievers in matters of ideology and belief is relatively secondary. If we then one-sidedly emphasize this difference, even to the point of giving it primary importance–for example, by discriminating against and attacking the mass of religious believers, while neglecting and denying that the basic political and economic welfare of the mass of both religious believers and nonbelievers is the same–then we forget that the Party’s basic task is to unite all the people (and this includes the broad mass of believers and nonbelievers alike) in order that all may strive to construct a modern, powerful Socialist state. To behave otherwise would only exacerbate the estrangement between the mass of believers and nonbelievers as well as incite and aggravate religious fanaticism, resulting in serious consequences for our Socialist enterprise. Our Party, therefore, bases its policy of freedom of religious belief on the theory formulated by Marxism-Leninism, and it is the only correct policy genuinely consonant with the people’s welfare."

From “The Basic Viewpoint and Policy on the Religious Question during Our Country’s Socialist Period” (1982)
