The way this section is written is a bit confusing to me. Straw-man proposal (that I'm sure could be improved):

This Code prioritizes the safety of individuals, particularly those in marginalized communities, over the comfort of others. For example, the following behaviours are presumed to be acceptable even if they make some participants uncomfortable:

• Reasonable communication of boundaries, such as “leave me alone,” “go away,” or “I’m not discussing this with you”
• Communicating in a tone that is perceived by some to be uncongenial
• Critising oppressive behaviour or assumptions, such as those that are racist, sexist, or cissexist

Note that claims of "reverse"-isms including "reverse racism," "reverse sexism," and "cisphobia" are not acceptable.

That should be just an editorial change. However, it might also be good to explain the points about tone and reverse-isms a bit more.
