Be kind and be gentle.
You will not get a person to change their mind or point of view by criticism, rebuke and bad temper. All you will do is make them more entrenched in their point of view and they will probably dislike you. Kindness and the friendly approach and appreciation can make a person change their mind more readily than all the criticism and bad temper in the world. Encouragement and understanding is far more powerful than sarcastic venom. Be kind and be gentle you have no idea the road the other person is walking, and have pity on the life of the fault finder and the critic they have live with that constant critical voice in their heads about themselves. Be an inspired Artist who wants to make a positive difference in your world and encourage those around you.
