GIVEN that courts have ruled it is a violation of First Amendment rights to block speech in response to official government social media accounts...
AND GIVEN that the only right to express your First Amendment rights on these videos is to LIKE or DISLIKE...
THE REMOVAL of dislikes by youtube is a clear violation of the First Amendment rights of the entire CLASS of people who chose to dislike the video.
Drafting a lawsuit on this matter would create an opportunity for DISCOVERY, which would give amazing insight into the unlawful manipulation undertaken by youtube.
Punitive damages to follow.
