I think there is a lot to be said about keeping a positive mindset, but the world turns regardless of how it makes us feel
The vile things people say bother me too, but over time I found ways to not allow the vitriol to spur an emotionally charged response.
Its our individual responsibility to find ways we can catalogue the nonsense, express strongly opposing ideas, and be calloused enough to not have a meltdown every time. It's happening whether we see it or not
