It's infinitely more important to know why you've changed your mind regarding formerly held political stances/views instead of standing on the fact that you simply have the right to.
Apart from anything else, it's redundant to say 'I have a right to change my mind" because that's a self-evident truth. At the end of the day, if you are being dishonest about your reasoning behind the shift in outlook, tact, and mindset? That's the flex of a false prophet.
