I agree that anonymity increases the potential for toxicity. But you're basically saying that because of that you're only willing to discuss politics in private, which to my mind doesn't really count as engaging in politics in a meaningful way. Given the proportion of public discourse that takes place on the internet these days, it makes perfect sense to develop tools like these to improve its quality. Opting out to only engage in political discussion in private is in a way a privilege, that many feel they can no longer afford.
