You don't need to tolerate certain behaviors and actions in fear of your reaction signifying to certain people that you are impacted by their actions. Self-love is doing what is best for your soul, regardless of how it appears externally to prejudiced eyes. It is within your right to be tired of someone's shit, acknowledge their presence is unwanted and inflammatory, and a repetitive imposition on your boundaries. And it is your obligation, if you value self-preservation, to either speak up on it or distance yourself without any explanation because a lot of the time, people know exactly what they are doing. And by continuing to tolerate it, you are setting a harmful precedent.
