Deleted "uncomfortable", left "threatened" (#1389)

Some discomfort is required for us to grow as people as well as a community. Requesting to not make people feel "discomfort" may be weaponized against people seeking help from the CoC team.
So, I deleted "uncomfortable and" from "uncomfortable and threatened". Not making people "threatened" suffices.
