Wow, thank you for makingme smarter. This is a very wise observation. I often think about where the line should be drawn on a continuum between artistic freedom and censorship.
I have come up with some clever ideas about it, but your observation is the most fundamental: unconditional freedom is never possible. It's true. If you have a body, you cannot have unconditional freedom. Also, when you set up a government you all agree to give up a little freedom for a lot of security.
Overall, I disagree with this opinion expressed, particularly because any unconditional freedom is impossible for people in human societies,and creative artists are no exception.---I made some small changes here.
Firstly , I won't deny that creative ----No need for "firstly." It's a stupid word. :-)
In conclusion, we should encourage those creative artists to exhibit their perfect works in any fantastic ways on condition that no negative effects resulted to public and our society.----This sentence seems unnecessarily complex. I think you should simplify it and shorten it. Then, add one more sentence as a sort of "final thought" about the whole issue.
