Here’s how I think about it. Each person is called to do something; we each have a God given purpose on this earth. You’re supposed to try to figure out what it is and then go about trying to do it. Part of knowing what your are called to do is paying attention to things that are in your life that you feel strongly about.
You see these images on youtube and feel a need to do something about it. I would think that you might be on to something there. I would suggest some prayer about it to try to figure it out what, if anything you’re supposed to do. I tend to be less formal about it… but each person will discern their calling in their own way. God’s pretty amazing that way! For me it was ongoing prayer through a crisis in my life (my calling is an offshoot of the crisis), asking for guidance and wisdom to know what to do, being open to receiving that wisdom, and a well timed conversation with my priest. I ended up with a stream of ideas about this calling that was like a flood; thankfully I had a computer nearby!
Really, pray about it and be listening for an answer. You will likely get an answer one way or the other, and perhaps in unexpected ways. Those feelings you have and ideas about what you should do… may just be your answer. Or maybe you will feel drawn in a different direction. You just need to be sure that whatever you are feeling the need to do is good and promotes God.
I hope this helps!!
