Evaluate your values. If a political party or movement no longer represents your values, don’t stick with it out of tribal loyalty. Stick with your own values instead. People might accuse you of “leaving” the party or movement, but in reality, it left you. Stay true to yourself.
Consider the beliefs of those you disagree with. Are there any valid points? Can you articulate their views in a way that they would agree with? If not, you don’t really understand their position. Remember that everyone believes they are fighting for a good cause.
Your identity is not defined by a political label. Don’t let yourself be defined by these categories, as they limit your personal growth and exploration.
