get the attention of the intended audience.
The fact he is a youth pastor doesn't really have anything to do with what happened. It was a ****ty person acting ****ty because they were there supporting Trump.
The entire video is on the pastor's youtube channel:

I didn't watch every second, but as I scrolled through, I didn't find anything about being a pastor or anything like that. Just being in favor of Trump.
This isn't to excuse the dude's behavior, he was clearly being a douche.
