Can you be a Christian and support the building of walls

I found at least 58 times the Bible mentions wall or walls. Some verses were neutral statements that there was a wall-many verse’s are positive and the walls were to protect God’s people with God’s approval. On the times God destroyed walls it was to punish people, including His chosen people Israel.
