How would an optional, official parser be toxic?

[Ranetsu-Akagane]

Alright, so people are saying public parsers will only cause problems if added. There is another outcome that could happen though. For example, say SE decided to add them tomorrow, I doubt an increase of harassment would just suddenly spike, I mean think about it people have been asking for an official parser for a long time now. I believe people will try to be very careful about how they use it, as to avoid having it removed.

There will be some that will still abuse it sure, but I don't think it would happen too much. Also, people would really need to learn to understand if someone says your damage is low, that it's not a personal attack, but that's just my opinion on the matter.
