Regardless of whether or not the act of protesting at a church service is acceptable, the protesters in this case were there to confront Christians with their own standards. These were Christians saying, how can you profess to hold this faith and do nothing while this shit's going on? The aim wasn't to tear down Jesus. It was to tear down the idea that Jesus would support ICE.

In this case, it certainly is because Lemon and the Black Lives Matter crew said they were there to make them uncomfortable and shut them down and basically bully them into their political form of thinking.
