The vice PM of Belgium already admitted they did, as you'll see below. But first, let's look at the song so many Muslims (along with the usual cadre of leftist apologists) sang in the days following the attacks on Brussels airport and rail station?
The above video gives other examples of the use of this song, which appears to be one of the very few in Islamic tradition, as Islam forbids recreational music.
It appears to celebrate Islamic victories. But you be the judge. Check the Wikipedia on this song and its purpose.
One would imagine that if a person or group were to pick a song to sing after an attack to show solidarity with the victims, a song like that one wouldn't be chosen.
Then we have the VP of Belgium admitting openly there was celebration by the Muslim community in parts of Brussels.
THE HAGUE, Netherlands (JTA) – In the days following terrorist attacks in Brussels, street celebrations broke out in several places in Belgium, the county’s vice prime minister said.
Jan Jambon made the statement about the March 22 bombings, which killed 35 people, on Wednesday during a symposium titled “Terrorism, Israel and International Law” and organized by the Dutch anti-racism and pro-Israel lobby group CIDI, or the Center of Information and Documentation on Israel, in The Hague.
One wonders if the lack of multicultural awareness is the problem here. We keep imagining that other cultures mean exactly what we would when we do things such as sing songs.
Real multiculturalism would require us to understand fundamentally different values and legal systems than ours, and then decide if they have any place in our own lands.
Real multiculturalism is not just inviting everyone in and pretending they really are the same as we are.
What the extreme left does is “pretend” that the values in other cultures are the same as ours, that Islamic values are the same.
And when we point out that these other values are fundamentally different than ours, the left then accuses us of “racism” rather than accept the differences in other cultures.
That isn't multiculturalism. That’s civilizational suicide.
