Use them! They're good!
It's not just about letting peoole opt in to what you're talking about, it also lets people scroll their timelines faster to get to the kinda shit they wanna read.
You're not braver, stronger, cooler, or more resilient for not using CWs, and if you react poorly to people asking you to share space in a halfways decent way, maybe I think you're a jerk?
Like, everyone should be able to browse their local and federated timelines. So use CWs.
