@gamingonlinux Tbqh, I've never had issues with tone policing (in a rude way), but a *lot* of abusive stuff is (thankfully) already blocked/filtered/removed by the awesome mods. Sometimes I just see a notification of some shit, want to report it and it's already gone :3
Most time, I just don't notice.
Whether or not something should be behind CW is, in the end, though simply a very personal preference. Sexual stuff? No CW for me. There are a *lot* of traumatized people on here (actually, the fedi was built by and for them, the CW culture is much older than the Twitter exodus and was never questioned... until now) and we cannot expect them to tell us *why* this seemingly arbitrary thing may be a trigger.
In the end, it's: Either CW or the person cannot follow you. Which you may be fine with, or, in the spirit of inclusion, try to think of using the CW. It's your choice.
I personally, as one can see, often do *not* use CWs. I probably should more often as I often post a lot of quite heavy stuff, but I'm not used to it (yet). For now, I cannot recommend those people to follow me. But I do hope to change that.
