Altars and its energies

I share my room with someone who is Christian and have a Christian Altar, used to pray and all. I have my own altar, the person is ok with this although do’t know exaclty why I use it haha
Could any of the spirits that I summon be offended or ignore me or something like this because of my roomsmate altar?

Doubtful, I think. Suppose a person imprisoned in a horrible Turkish prison decides to pray for the healing of the world. Would the deity addressed be offended and not respond because of the filth and cruelty around?
