Watch This 'Kids React' Kid Change His Mind On LGBTQ Issues As He Grows Up

The always entertaining "Kids React" videos have gone viral for showing kids reacting to current events, pop music from before they were born, and food from different cultures. 

And because they have used many of the same kids in these videos, it's possible to trace their evolution on different social issues—like Twitter user VelvetPJM did when he noticed that one of the kids in the videos got progressively more tolerant about same-sex marriage in videos taken at different times in his childhood.
