The Dutch government is ignorant, scared and cowardly. Instead of doing what has to be done in defense of our freedom, they rather submit to the will of the enemy. That means lowering the flag. LITTERALY!!!
Update (March 21):
Today a majority in parliament (NL), including the ruling parties, was angry about the news of lowering the flag. As often is the case in Dutch politics, this was an empty ritual and nothing changed. The flag stays down.
