Minecraft wiki entry for Things_not_to_do, associated text: This is important for people with villagers in their base. If your base has lots of fortifications and you are experienced enough to tackle a raid without losing any villagers, it may be a good idea to do a raid in your base. However, for other players, it is not the best idea. For example, you can risk losing valuable villagers, even if you blocked them off (attacks from vexes), ravagers destroying your crops and custom trees, pillagers shooting wooden buttons, entities and pressure plates, activating redstone contraptions and/or destroying minecarts, boats, armor stands, item frames, etc. If you are fighting near your spawn point and get killed by your spawn point, you end up stuck in a death loop because you respawn and get killed by the raider again. (This is not as much as a problem for experienced players) If you have to do a raid, consider blocking those things off and summoning as many iron golems as possible, especially near crop farms and villager trading halls, as the raiders can destroy it.
