Ideologies are quite complicated things. As you've mentioned, there are varying opinions whether there are good or bad ideologies. Having an ideology can start conflicts, hate, or discrimination. But having an ideology can also incite compassion, empathy, or peace. The problem arises when ideologies clash.

As mentioned once again, when you have an ideology, you already have your mind set up on what you want to believe and here. From this, it makes you wonder if it's actually better to have no ideology at all.

Without following a particular ideology, you remain open and free to everything. Or perhaps you don't have to completely let go of the ideologies you live by. Perhaps people just need to be more open-minded, in general. Then perhaps everyone would live more peacefully and with less conflicts.
