Freedom in general is not absolute,meaning if we stepped on another person's right to freedom then that is where we draw our limit. Freedom of expression is something that might sound subjective, like saying "I don't care what other people say, I have a right to express myself in whatever way I want." Sure that is your right but if exercising that right means hurting someone else's feelings or causing badmouthing of people and disgracing them, then I guess your freedom of expression ends since you are not the only one affected with what you are doing. Positive self expression is highly suggested like having advocacy on several important social issues and upholding social responsibilities. One thing we should always remember is that our comfort should not cause someone else's discomfort.
