Book Reports / My topic for a persuasive essay on the novel 1984 (help with topic and thesis) [2]

I want my topic to be something to relate to the way in which Big Brother changes the way that the citizens think and stole all of their creative abilities.

So far I have this as a thesis,
By changing historical facts, projecting constant propaganda at the citizens, and censoring the media in which they do receive, Big Brother has stolen peoples right to think.

PLEASE HELP
