Interrupting a speech? Yes. It demonstrates a lack of maturity, decorum, and is completely unprofessional. Someone who pulls these shenanigans is unworthy of the role they were hired for. This isn't high school anymore. They were hired to perform productive work not be disruptive and play pretend activist.

You lost me at "pretend activist". This person put their job on the line for what they believe in, and in a public enough way that complete strangers are discussing it on the internet. That's real activism.
