It absolutely is being a troll. If you aren’t willing to associate yourself with your participation, that’s the definition of a troll.
With anonymous downvotes, they are already weaponized and used to suppress topics. Having publicly available voting means you can block people who are toxic downvoters and/or hopefully ban those people/bots that do that.
Let me say this again so I can be perfectly clear: **If you are not willing to own your participation on a public forum, you should not be participating on that public forum. Go to a private one. **
The rise of online toxicity is a direct correlation with anonymity. What’s even more egregious about your stance is the fact that if you want to be anonymous and maintain your anonimity, it’s easy to do: use a throwaway account or otherwise anonymous account on yours or any other lemmy instance. There is absolutely NO valid reason to not have your voting history public in the Fediverse. The privacy crowd can make that happen by having throwaway accounts (which can be banned for being toxic, etc…) and people who want to have civilized discussions can have that by blocking/banning problem accounts. Taking away the public nature of your participation ONLY encourages toxic behavior and the ONLY people advocating for private voting are either trolls or people who don’t understand the problem.
