There's no reason to call someone a troll. We can just ban them, since it's against the rules.
However, if we don't want to be so drastic, it's a bit hard to tell someone to stop trolling by avoiding the "T word". Using such terminology is effective because everyone knows what it means and you don't have to go any further. If a mod thinks someone is trolling, they will say so and that will be a warning before any further steps are needed.
I don't see why it's necessary for a mod to have to beat around the bush in this regard. If we think you're trolling, we tell you to stop trolling. Trying to be "PC" about something like this is ridiculous.
Also, if mods aren't supposed to "side against" anyone by calling them out on a problem, then I guess our jobs are useless.
