Is it permissible for a Muslim student residing with Christian students in Switzerland to place his belongings in a shared refrigerator that contains alcohol?

The questioner is advised to seek other housing because cohabiting with disbelievers poses a great danger to one's religion. If he is compelled to live with them, then it is obligatory upon him not to be content with their falsehood and to denounce their evil. There is no harm in placing belongings in a refrigerator containing alcohol, as long as he is compelled to do so and cannot pour it out.
