I am writing a term paper on semiotic theory to analyze online communication trend like hashtags. I am going to analyze #metoo and #heforshe. I need thesis statement for this.

We cannot write the thesis statement for you. You need to do that yourself. If you write it and submit it to the forum, one of us will try to help you with the English.

There is a thesis statement in your post. Just rearrange the words to make a statement that you are going to discuss and prove in your essay.
