Changing your mind doesn’t make you a hypocrite. Hypocrites are people that claim to have certain morals, but act differently. That’s not people that change opinions.
Example of a hypocrite:
“The Bible says homosexuality is wrong and everything in the Bible is right, sorry I have to be against gay rights” * proceeds to have affairs, use the lord’s name in vain, and does many other things the Bible considers wrong*
This person isn’t a hypocrite if they change their minds about gay rights, or even went back and forth.
They are a hypocrite because they claim their actions are guided by the Bible, yet clearly they aren’t because they conveniently choose what to follow.
