I like the main focus on how social media abuses the 1st Amendment. That could be your focus and then your research would be to find out how and your supports would be the ways that this abuse occurs and the outcomes.
One small note: when making a thesis statement all we need is the claim. We don’t offer the “because” justifications in the statement. Those are the body arguments and, in order to keep the reader engaged, should be revealed as you argue them and not outright stated in the thesis statement.
So if you go with the suggestion above, your thesis statement might be: “Social media abuses the First Amendment, and that is an abuse of us all.”
